Preface

This manual provides planning, site preparation, preinstallation, and
installation information and recommendations to ensure a successful
PDP-IS installation.
Digital Equipment Corporation (DEC) will provide customer assistance in all phases of site planning. The final lay-out plan should be
approved jointly by the customer and DEC.
Planning considerations include: floor-plan layout for equipment;
environmental considerations; fire and safety precautions; and storage
facilities for paper tapes, Teletype@ paper, punch cards, plotter paper
supplies, etc.
Site preparation is keyed basically to the customer's applicable requirements or desires and can, therefore, range from providing the
required source-power circuit to the construction or remodeling of
the selected installation site.

Chapter 1
Planning

1.1 SITE PLAN

1.3 SYSTEM LAYOUT

Adequate site planning and preparation can simplify the installation process and result in an efficient, reliable PDP-IS
System installation. DEC Sales Engineers and/or Field
Service personnel are available for counseling and consultation with customer-designated personnel regarding objectives, course of action, and progress of the installation.

PDP-IS Systems can be ordered under three types of layout plans. The three types are:
Plan A - an unmodified, standard PDP-IS System
configuration. This plan provides a fixed configuration including standard cable lengths to free-standing
peripherals;

The customer's planning staff should prepare a list of the
actual components to be used in the installation. This list
should include such items as tape-storage cabinets, work
tables and desks, and any other items pertinent to the
customer's computer application.

Plan B - a configuration similar to Plan A except
that either the cabinet-mounted peripheral configuration or the free-standing peripheral locations are
different from DEC specifications;

Primary planning considerations are the availability and
location of adequate power and the existence of fIfe and
personnel safety precautions. If the existing environmental
conditions dictate, air-conditioning and/or humidifying
equipment installation can become part of the site planning
and preparation program.

Plan C - a special PDP-IS installation dictated by
the customer's application and built by DEC's Computer Special Systems group. For such a plan, the
customer should prepare a layout of PDP-IS cabinet
and peripheral equipment locations and submit the
layout to DEC for approVal. If the PDP-IS control
console is to be remotely installed, the distance from
the console to the PDP-IS must be specified by the
customer. The appropriate interconnecting cable can
then be supplied by DEC.

1.2 SPACE REQUIREMENTS

NOTE

Space requirements are determined by the specific system
configuration to be installed and, when applicable, provision for future expansion. To determine the exact area
required for a specific configuration, a machine-room floor
plan layout is helpful. When applicable, space is provided
in the machine room for storage of tape reels, printer forms,
card fIles, etc. The integration of the work area with the
storage area depends on the work-flow requirement between
areas.

Advanced notice for systems of
special (non-standard) configuration is required and is subject
to approval by the Special Systems engineering group.
Operational requirements determine the specific location
of the various free-standing peripherals of the system.
Dimensions, weights, and service clearances of free-standing
peripheral equipments are shown in Table 2-5. Standard
and maximum cable lengths are shown in Table 2-6. Computer peripherals and/or the remote console must be

In large installations where test equipment is maintained,
DEC recommends that the test equipment storage area be
within or adjacent to the machine room.

I-I

operational safeguards for personnel and system components.

located so that the length of connecting cables will not
exceed maximum limits. The following points should be
considered when planning the PDP-IS layout:

Q.
Q.

Ease of visual observation of input/output devices
by operating personnel. .

b. Adequate work area for installing tapes, allowing
access to console, etc.

If an overhead sprinkler system is used, a "dry
pipe" system is recommended. This type of
system, upon detection of a fIre, removes source
power to the room and then opens a master valve
to ftll the room's overhead sprinklers.

b. If the frre detection system is of the type that
shuts off the power to the installation, a batteryoperated emergency light source should be provided.

c. Space availability for contemplated future expansion.
d. Proximity of the cabinets and peripherals to any
humidity-controlling or air-conditioning equipment.

c. If an automatic carbon-dioxide frre protection
system is used, an alarm should sound on release
of the CO 2 to warn personnel within the installation.

The fmal layout is reviewed by the DEC Sales Engineer
and in-house engineering personnel to ensure that cable
limitations are not exceeded and that proper. clearances
are maintained.

d. If power connections are made beneath the floor

of a raised-floor installation, waterproof electrical
receptacles and connections should be used.

When applicable, the DEC Pield Service Branch Manager
provides a scaled layout of the Pield Service Engineering
equipment to be installed in the computer room.

e. An adequate earth ground connection should be
provided for the protection of operating personnel.

1.4 INSTALLATION CONSTRAINTS
1.6 ENVIRONMENTAL CONSIDERATIONS

The route that the equipment is to travel from the receiving area to the installation site should be studied and
measurements taken to facilitate delivery of the equipment.
All measurements and floor plans should be submitted to
the DEC Sales Engineer to ensure that the equipment is
packed to suit the installation site facilities. If possible,
this information should be provided upon placement of
the order. Any restrictions (such as bends or obstructions
in the hallways, etc.) should be reported to DEC.

An ideal computer room environment has an air distribution

system which provides cool, well-fIltered, humidified air.
The room air pressure should be kept higher than the pressure of adjacent areas to prevent dust infIltration.

1.6.1 Humidity and Temperature
If an elevator is to be used for transferring the PDP-! 5 and
its related equipment to the installation site, DEC should
be notified of the size and gross weight limitations of the
elevator. The equipment can then be packed and shipped
accordingly.

The PDP-IS System is designed to operate in a temperature range of from SOap (lO°C) to 1lOop (43°C) at a
relative humidity of 20 to 90 percent with no condensation. However, typical system confIgurations using
input/output devices such as magnetic tape units, card
readers, etc., require an operational temperature range
between 6S op (lSoC) and SOop (27.S 0 C), with 40 to 55
percent relative humidity. Nominal operating conditions
for a typical system are a temperature of 70° F (21 ° C)
with a noncondensation relative humidity of 45 percent.

1.S FIRE AND SAFETY PRECAUTIONS

The following fire and safety precautions are presented as
an aid in providing an installation that affords adequate

1-2

must be notified of the special conditions upon placement
of the order.
Tables 3-1, 3-2, and 3-3 show the heat dissipation factors
of the PDP-IS System and its peripheral equipment. When
used, computer room air-conditioning equipment should
conform to the requirements of the "Standard for the Installation of Air-Conditioning and Ventilating Systems
(non-residential)", N.F.P.A. No. 90A; as well as to the
requirements of the "Standard for Electronic Computer
Systems", N.F.P.A. No. 7S.

1.6.6 Qeanliness
The following precautions are recommended by DEC to
ensure optimum PDP-IS operation:

a. Do not use steel wool for cleaning floors in the
computer room. The metal fibers can enter the
cabinets and short the electrical components.

1.6.3 Acoustical Damping

b. To prevent air flow interference, do not place
material on top of the cabinets.

Some peripheral devices (such as line printers and magnetic
tape transports) have a high noise level. In installations
that use a group of high noise-level devices, an acoustically
damped ceiling reduces the noise.

c. Use a nonconductor type nozzle when vacuuming
to minimize the possibility of an electrical accident.
d. Avoid spilling liquids (coffee, soda, etc.) on the

equipment and operating controls (e.g., console
switches, Teletype keys and controls).

1.6.4 Lighting
If cathode-ray tube peripheral devices are part of the
system, the illumination surrounding these peripherals
should be reduced to enable the operator to conveniently
observe the display.

1.6.7 Static Electricity
Static electricity can be an annoyance to operating personnel and can (in extreme cases) affect the operational
characteristics of the PDP-IS and related peripheral equipments. If carpeting is installed on the installation room
floor, it should be of a type designed to minimize the
effects of static electricity. Flooring consisting of metal
panels, or flooring with metal edges, should be adequately
grounded.

1.6.S Special Mounting Conditions

If the PDP-IS will be subjected to rolling, pitching, or
vibration of the mounting surface (e.g., aboard ship), the
cabinetry should be securely anchored to the installation
floor by mounting bolts. Because such installations require modifications to the PDP-IS System Cabinets, DEC

2.2 SYSTEM EXPANSION

STANDARD CONFIGURATIONS

PDP-IS Systems can be expanded to the cabinet configuration shown in Figure 2-5 and can be further expanded to
include up to three memory multiplexer cabinets. Memory
multiplexer maximum configuration is shown in Figure 2:"6.
Table 2-5 lists all peripheral devices available with PDP-IS
Systems, and Figure 2-5 illustrates the physical location of
the device controllers and cabinet mounted devices. Freestanding peripheral devices are not shown. Peripherals such
as disks, CRT displays, industry-compatible magnetic tape
transports, card readers, and line printers are all freestanding; their proximity to the PDP-IS is determined by
the length of the cable interconnecting the device and its
controller (refer to Table 2-6). An system expansion
cables are supplied by DEC.

There are four standard PDP-IS System configurations;
components are detailed in the table and figure indicated.

a. PDP-lS/IO (Table 2-1, Figure 2-1)

b. PDP-l 5/20 (Table 2-2, Figure 2-2)

c. PDP-l 5/30 (Table 2-3, Figure 2-3)

Chapter 3
Predelivery Preparation

3.1 GENERAL

3.1.2 Three Months Prior to Delivery

The size of the system to be installed is the prime consideration in determining the degree of planning and site
preparation required. The following general schedule is
suggested as a guide in site preparation and planning.

The installation layout should be agreed upon by the
customer and DEC three months prior to the delivery
date. All cables are specified and ordered at this time.

3.1.3 One Month Prior to Delivery
3.1.1 Receipt of Installation Manual
The DEC Sales Engineer visits the installation site one
month prior to the delivery date to determine the specific
requirements for moving system components from the
delivery van to the installation site. Any installation site
restrictions and/or receiving area-to-installation site constraints should be noted and reported to the DEC Sales
Engineer.

The following course of action should be initiated upon
receipt of the Installation Manual.

a. Read the Installation Manual and consult with
DEC regarding preinstallation planning.
b. Determine the location of the installation and the

system configuration. If applicable, make an installation lay-out diagram using the information
in Table 2-5 and Figure 2-5 of Chapter 2. Figure
3-1 illustrates basic PDP-15 cabinet dimensions.

3.1.4 One Week Prior to Delivery
Installation of air-conditioning equipment, electrical and
power facilities, lighting, etc., should be completed one
week prior to delivery.

c. Determine the placement of air-conditioning, lighting, power receptacles, etc.
d. Check the size of doors, passageways, elevators, etc.,

that could create receiving and/or installation
problems. If a problem is noted, DEC must be
informed I month in advance of the shipping
date. Special packing/shipping provisions can then
be implemented.

3.2 CABLING
DEC cabinet interconnecting cables are of standard lengths
and are factory installed. If the cabinets must be shipped
separately because of shipping or receiving restrictions, the
cabinet interconnecting cables are reconnected at the installation site. The termination point of each cable is
identified.

e. Determine the power requirements of the system.

This information is provided in Section 3.3, System Power Requirements.

Cables for a Type B or C plan as outlined in Chapter 1 are
measured and ordered in accordance with the DEC-approved
installation layout. The part number and required cable
length is specified by the DEC Saies Engineer for each
cable or group in the PDP-15 System.

f. Check the local delivery date for all power and
air-conditioning equipment to ensure delivery and
installation of these items prior to deiivery of the
PDP-15 System.

Cable change requests for any reason other than the above
(such as installation floor plan lay-out changes) are considered by DEC on a special request basis only. Such
cable changes can affect the delivery time of the PDP-IS.

All cable lengths should be as short as possible, and under
no circumstances should any of the maximum lengths be
exceeded. External interconnecting cables should be protected from damage by installing a protective metal cover
over the cables in a manner that will not present a safety
hazard to operating personnel.

3.3 SYSTEM POWER REQUIREMENTS

If additional equipment is added to the system after the
PDP-IS has been installed, only the standard cables to
connect the new equipment into the system are supplied.
Configuration control is maintained by DEC; therefore,
all additional equipment changes must be submitted to
DEC for approval. This procedure facilitates cable layout
and planning.

Figures 3-2 and 3-3 show the total current requirements of the PDP-IS System. Tables 3-1 and 3-2 give
the power and Btu/hr rating of each option and peripheral
in the PDP-IS Systems. Additionally, Table 3-2 provides
the current requirements for each free-standing peripheral.
Table 3-3 provides the power requirements for the standard
PDP-IS configurations_

all currents associated with each cabinet and peripheral device. From this data, the type and quantity
of ac connectors can be determined. Provide one
ac connector for each cabinet and one ac connector
for each free-standing peripheral.

The total current required by the PDP-IS installation can
be determined by the following procedure:

From the PDP-IS System Configuration Chart,
Figure 3-2, determine the equipment and corresponding cabinet requirements of the particular
system to be installed. Repeat this procedure for
the free-standing peripheral devices (see Figure 3-3).

Even though an installation may not use all the options in
a particular cabinet, it is recommended that adequate ac
power for the entire cabinet be provided.
Example:

b. Using Table 3-2, determine the current required by

each free-standing peripheral device (see Figure 3-3).

An installation requiring bays 00, 1R, and 4R requires
the following three ac outlets:
(1) 2SA (ISOA surge)*
(I) lOA (2SA surge)*
(1) 3.SA (IIA surge)*

c. The total current required by the PDP-IS installation can now be determined by adding together

*These amperages are applicable when using lIS Vac 60 Hz power.

3.4 SOURCE POWER REQUIREMENTS

3.4.1 Primary Power Receptacles

The PDP-IS can be operated from a 100, 115,200,215, or
230V 50 Hz ac power source; or from a 120/240V 60 Hz
ac power source. The primary ac operational voltages
should be maintained as closely as possible to the nominal
value.

The installation site primary power line must terminate
in Hubbell wall receptacles (or equivalent) to be compatible with the PDP-IS power line Hubbell connector. The
Hubbell wall receptacle part numbers are shown in Table
3-5. Figure 3-5 shows the primary power wall receptacles
and the points where the site primary power lines are terminated. One receptacle is required for each cabinet and
one for each free-standing peripheral.

Line voltage tolerance must be maintained within ±15 percent of the nominal values, and the 50/60 Hz line frequency
should not vary more than ±2 Hz.
Primary power to the system should be provided on a line
separate from lighting, air-conditioning, etc., so that computer operation will not be affected by voltage surges or
fluctuations.

3.4.2 Service Outlets

The PDP-IS cabinet grounding point should be connected
to the building power transformer ground or the building
ground point.

Duplex ac outlets should be provided to power test equipment when maintenance tasks are performed. The duplex
outlet (see Figure 3-5) should be located near the PDP-IS
and its related equipment and should be rated at 120 Vac
±15%, 50/60 Hz, 15 or 20A. These outlets should be
separately fused and switch-controlled and should be installed approximately 10 feet apart.

Any questions regarding power requirements and installation wiring should be directed to the DEC Regional
Sales Engineer.

4.8.1 General
The following infonnation comprises a check for proper
connection of the Model 715 power-supply transfonner Tl
and plug Pl5 before power is applied to the PDP-15. The
main primary power source should be protected by 40A
circuit breakers.

4.7 PRIMARY AC POW"ER CABLES
4.8.2 Transformer Tl Connections

Primary ac power cables are three-wire cables that interconnect the installation-site source power to the PDP-I 5
power supplies. The cables are connected at the factory
to the PDP-15 power supplies for either 50 Hz or 60 Hz
operation. All cabinets (excluding cabinets having disks
and DECtapes mounted in them) have a self-contained
power supply and an ac power cable.

The Tl primary windings have been connected at the
factory for either 50 or 60 Hz operation. However, before
proceeding to the following sections~ ensure that the
jumpers are correctly connected to correspond to the installation site power-line voltage. T 1 connection information is provided in Table 4-2 and Figure 4-5. The infonnation is also provided on the rear cover of the main
power supply. The T 1 connectors are shown in Figures
4-6 and 4-7.

Each wire in the power cable is color-coded (refer to
Table 4-1). The power cable for the Mod~l 715 power
supply is connected to tenninal strip TS3 (see Figure 4-5).

Appendix A
Maintenance And Service Options

Coverage of 24 consecutive hours, Monday through Friday,
begins on Monday of each week at 7 a.m. and terminates on
Saturday of each week at 7 a.m.

Digital Equipment Corporation's Field Service Organization
offers a wide range of services for DEC equipment users.
Customers may choose from a broad selection of Service
Contract Options and Per-Call Service or Depot Repair
Maintenance plans to ensure optimum operating efficiency
for their DEC equipment.

The Saturday period of coverage consists of eight consecutive hours of on-call coverage during the period 7 a.m.
through 6 p.m. The Sunday period of coverage consists of
eight consecutive hours of on-call coverage during the
period 7 a.m. through 6 p.m. As with the principal period
of coverage, Saturday/Sunday coverage can be extended
to 12, 16, 20, and 24 hours.

A.I SERVICE CONTRACTS
Service Contracts are tailored to the user's individual operation. In addition to providing all the necessary parts,
labor, and test equipment required for remedial maintenance, Service Contracts also ensure system reliability by
providing scheduled, systematic preventive maintenance.
Planning and budgeting are greatly simplified because
these contracts allow the user to fill his maintenance needs
at a fixed, monthly charge.

An on-site resident engineer plan can be implemented if
the size, complexity, and/or critical nature of an installation require such a plan. The services of a resident engineer consist of 40 hours of coverage during the normal
work week. In addition, all necessary spare parts, materials,
and test equipment are physically stationed at the user's
site to further ensure prompt and efficient remedial and
preventive maintenance services. Monthly rates for contracted coverage are supplied on request.

A.I.I Service Contract Options
On-Call Service Contract Coverage provides remedial maintenance when the customer notifies DEC of a system malfunction. Preventive maintenance is scheduled and performed during the period selected by the user. The principal period of coverage consists of eight consecutive hours
of on-call coverage during the period 7 a.m. through 6 p.m.,
Monday through Friday. The user can extend his coverage
from the principal period by selecting:

There are no additional charges for travel in connection
with service contracts except for remote installations.
Remote installations are defined as installations located at
a distance greater than 100 miles from a DEC Field
Service Office.

A.I.2 Eligibility for Service Contract Coverage

a. 12 consecutive hours of on-call coverage

A Pre-Service Contract Inspection is required for installations that were not under DEC's maintenance responsibility immediately prior to the requested commencement date of the service agreement. All charges associated
with this inspection (including travel, labor, and parts) are
billed to the user at the prevailing standard DEC rates. A
minimum charge is associated with the Pre-Service Contract

b. 16 consecutive hours of on-call coverage

c. 20 consecutive hours of on-call coverage
d. 24 consecutive hours of on-call coverage

A-I

A.3 DEPOT REPAIR

Inspection. No inspection is required for service agreements that are scheduled to commence immediately after
the expiration of a standard DEC Warranty or Service
Contract.

Depot repair facilities have been strategically located
throughout the world to enable users of DEC equipment
to receive prompt, efficient service on many standard DEC
options. Depots are also fully equipped to service and
completely rebuild, if necessary, ASR and KSR Teletypes.
Further, users of DEC equipment interested in purchasing
rebuilt ASR and KSR Teletypes, or using their existing
Teletypes on a trade-in basis toward the purchase of new
machines, are urged to contact their nearest DEC Field
Service Office for further information.

A.2 PER-CALL COVERAGE

Per-Call Coverage is designed to permit the users of DEC
equipment to obtain service on a time and materials basis.
Requests for Per-Call Coverage are considered after requests
for Service Contract Coverage; thus, only users with their
own service capabilities or users who are not critically tied
to their equipment are encouraged to use this form of
coverage. All charges for Per-Call Coverage are computed
on a portal-to-portal basis. Commercial travel expenses
related to the performance of services are billed as incurred.
Material and parts consumption associated with Per-Call
Coverage is charged to the user at the prevailing prices
listed in the DEC Spare Parts Catalogue. Labor charges
for Per-Call Service are on an hourly basis and are available on request.

Depots are fully equipped and staffed with experienced
personnel to offer rapid and economical repair services
to the DEC customer. At the user's option, a national
transportation firm, contracted by DEC, can be used to
route equipment to and from the depot facility.

Charges for depot service, in addition to freight and insurance both ways, are computed per hour for labor,
parts, and material consumed. There is no minimum
charge for the use of the depot repair facility.

A minimum charge for Per-Call Service applies to each
service call; in addition, DEC neither implies nor guarantees the availability of Per-Call Coverage outside the hours
of 7 a.m. through 6 p.m., Monday through Friday. Users
in need of extended periods of coverage are encouraged to
use the many Service Contract options available.

Customers wishing to use the depot facilities are requested
to contact the nearest depot and furnish the following:

Users receive an invoice for all service rendered under PerCall Coverage. It is the responsibility of the user to inform
the DEC Field Service Office servicing the equipment of
any special billing instructions related to the use of PerCall Coverage. Such notification must be rendered before
the commencement of any services on the part of DEC; in
the absence of such notification, invoicing shall be accomplished in accordance with procedures determined by DEC.
Installations req uiring Purchase Orders for the authorization
of work performed on a time and materials basis are encouraged to submit a blanket order for one year's duration
to cover such services. There will be no· additional charge
for processing and administering such blanket orders.
Terms for all services provided on a per-call basis are net
30 days. In addition to the charges outlined above, customers are also charged for all federal, state, municipal,
or other government, excise, sales, use, occupational, or
like taxes, now in force or enacted in the future, incurred
as a result of the performance of per-call service. Installations enjoying tax exemption are requested to present their
current exemption certificate number at the time that PerCall Service is rendered or with the submission of the
blanket Purchase Order.

the total charge is equal to the sum of the option installation charges plus a one-time travel charge.

Customers wishing to expand their existing systems by
purchasing additional DEC options may elect to have the
installation of the new equipment performed at a fIxed
rate to facilitate the budgeting and purchasing processes.

For the purpose of performing field installations, remote
locations are defmed as areas outside those areas normally
serviced by DEC or its subsidiaries. Requests for installations in remote locations are considered on an individual
basis. Field installations are performed from 7 a.m. to
6 p.m., Monday through Friday. A minimum charge is
associated with a field installation.
