2–6 SITE PREPARATION

2.4 HA32B UPS BATTERY CABINET
Before installation of the UPS Battery Cabinet, consideration must be given to the
environmental and the structural integrity of its intended location. The electrical wiring
must meet both local and national electrical codes.

2.4.1 Environmental Considerations
•

Air Temperature: The recommended operating temperature is 25°C (77°F).
The UPS Battery Cabinet adds an insignificant amount of heat to the environment
when fully charged, and normally is not calculated when sizing the capacity of an air
conditioner.

•

Air Quality: The UPS Battery Cabinet should be provided with air free of
contaminants such as excessive moisture, vapor, flammable gases, chemical fumes,
salt, or excessive dirt and dust.

•

Ventilation: The UPS Battery Cabinet is designed for operation on a raised
computer room floor or a concrete floor. Cooling air for the UPS Battery Cabinet
is typically provided through a perforated floor tile on a computer room floor. Cutouts
are necessary for bottom access cables only.

•

Humidity: 10 to 90%, noncondensing.

•

Altitude: Sea level to 2,134 meters (7,000 feet).

2.4.2 Mechanical Considerations
•

Floor Tile Cutout: A floor tile cutout is required to provide bottom cable entry to
the UPS Battery Cabinet. When the UPS Battery Cabinet is installed on a raised
computer floor, its weight should be evenly distributed. Locate the corners of the UPS
Battery Cabinet as close as possible to the corners of the tiles. Figure 2–4 gives the
nominal dimensions and location for this cutout.

SITE PREPARATION 2–7

•

Floor Loading: The weight of the UPS Battery Cabinet must be considered when
planning the equipment or computer room layout. The floor must be capable
of supporting the weight of the UPS Battery Cabinet, as well as all associated
equipment (UPS, air conditioning system, furniture, and so forth.) as oriented on
your equipment or computer room layout. Particular attention to weight must be
given when the equipment is installed on a floor raised above ground level. The
approximate weight and dimensions of the UPS Battery Cabinets are listed in
Table 2–2.

•

Service Area: The UPS Battery Cabinet requires rear, top, and front access for
servicing. At least 610 mm (24 in.) at the rear of the unit should be allowed for
service. At least 914 mm (36 in.) of clearance above the unit should be allowed for
normal ventilation. At least 1,219 mm (48 in.) in front of the unit should be allowed
for service. This will provide sufficient area to allow the pull-out rack assembly to be
removed from the unit.

3.3 HANDLING
The HA3000 series of UPS equipment is designed for handling primarily from the
bottom (Figure 3–1). For HA3000 series UPS cabinet dimensions and weights, refer to
Chapter 2. The individual cabinets are mounted on a shipping pallet and covered by a
cardboard shipping carton. They are designed to be moved by a pallet mover, a rolla-lift
(Models M-4, M-4-6, or CD-6), or a forklift-type truck. The front and rear lower cover
plates of each cabinet are removed for shipment. The HA32A UPS cabinet has a drawout input air filter located under the enclosure, which is also removed for handling or
transit. The UPS draw-out input air filter can be pulled out from beneath the enclosure
once the front lower cover plate is removed.
The HA3000 series equipment cabinets can be handled or moved by overhead equipment
after they have been fitted with the necessary slings and spreaders (Figure 3–1).
Use the following procedures to move the HA32A UPS cabinet, the HA32B UPS Battery
Cabinet, the HA32C/D/E UPS Auxiliary Cabinet, the HA33D/F UPS CSA Cabinet, or
the HA32J/K UPS Distribution Cabinet from the shipping truck to the final installation

NOTES:
1. As a minimum, bypass ac input (MAINS2) power should match the UPS output rating. The bypass ac input
should have a continuous rating of 125% of the UPS output power rating, however, to supply fault-clearing
current.
2. Battery wiring should be sized to keep the total cable voltage drop to less than 0.5 Vdc at the current
shown.

4–4 INSTALLATION

4.2.2 Bypass AC Input (MAINS2) Connection
The bypass ac input connection is three-phase, four-wire Wye1 plus equipment ground.
The phase rotation must be A, B, C. Bypass ac input (MAINS2) voltage must match the
UPS output voltage. Refer to Table 4–1 for the nominal bypass ac input current at the
nominal bypass ac input voltage specified. Size the bypass ac input cables and upstream
protection devices accordingly.
CAUTION
Single-point grounding: The UPS cabinet is shipped from the factory with
the neutral bus tied to ground with a jumper that has a yellow tag attached
(Figure 4–2). If the UPS cabinet bypass ac input (MAINS2) source already
has the neutral grounded (either from the facility power source or from the
UPS Auxiliary Cabinet/CSA Cabinet isolation transformer), remove the jumper
between the neutral and ground busbars in the UPS cabinet. This prevents a
ground loop problem.

Proper grounding procedures are essential
to the operation of an Uninterruptible Power
System (UPS), personnel safety and critical
load equipment protection. The National
Electrical Code (NEC) and applicable local
codes must be followed. Please refer to
Installation Manual (EK-HA32X-IN)
for various load configurations and
recommended grounding schemes.

INSTALLATION 4–9

4.3 HA32B UPS BATTERY CABINET
The UPS Battery Cabinet is shipped with the lower front and lower rear panels removed.
The hardware needed to install these panels is in place.

4.3.1 General Installation
The UPS Battery Cabinet is designed for use with the HA32A UPS equipment only.
Generally, the UPS equipment is installed as close as possible to the UPS Battery Cabinet
(recommended less than 6.1 m [20 ft]). This is done to minimize the size of the battery
power conductors that must be run between the UPS cabinet and the UPS Battery
Cabinet. Excessive voltage drop in the battery power conductors causes a decrease in
the anticipated protection time. The maximum dc current required to flow between
the UPS Battery Cabinet and the UPS cabinet with which it is intended to operate is
shown in Table 4–2. The maximum cable voltage drop should be limited to 0.5 Vdc at the
maximum dc current.
CAUTION
When multiple UPS Battery Cabinets are installed, the lengths of all dc power
cables should be the same. This is to prevent differences in cable voltage drop
within the operating UPS system.

4.6.4 Non-Digital Output Cables
Digital employs a "Single Point Grounding Strategy" to provide a single point of reference
for computing equipment. If the customer decides to purchase Digital’s power distribution
cable assemblies (UL Listed), the single point reference goal will be achieved by the very
design and implementation of the cables.
The body of these cables are constructed of a liquid-tight flexible metal conduit. They
employ an isolated ground type receptacle and a metal outlet box. The internal
conductors provide the appropriate number of insulated phase conductors (receptacle
dependent), an insulated neutral (receptacle dependent), and two insulated ground
conductors. In the cable, one of these ground conductors is attached to the grounding
lug on the receptacle and the other is attached to the metal outlet box. At the UPS
Distribution Cabinet end of the cable, both ground wires are connected to the same
ground busbar, the phase conductor(s) are connected to a circuit breaker, and the neutral
wire is connected to the neutral busbar.

4–36 INSTALLATION

If an electrician constructs the power distribution cables, it is HIGHLY
RECOMMENDED that these cables be of similar construction as those described in
the previous paragraph to maintain Digital’s "Single Point Grounding Strategy" for
maximum computer system reliability.

A
ELECTRICAL CONSIDERATIONS

A.1 GENERAL
Proper grounding procedures are essential to the operation of an uninterruptible
power system (UPS), personnel safety, and critical load protection. It is the
customer/customer electrician’s responsibility to ensure compliance with the
National Electrical Code (NEC, ANSI/NFPA 70) and applicable local codes.

A.2 TERMS AND DEFINITIONS
1. Grounded conductor: The branch of the circuit (usually the neutral) that is
intentionally connected to ground. This grounded conductor is part of the current
carrying circuit.
2. Grounding conductor: The conductor(s) that connects all exposed metal parts of
the equipment to the ground. This grounding conductor is NOT part of the current
carrying circuit.
3. Separately derived source: Article 250-5(d) of the NEC defines a separately
derived source as:
A premises wiring system whose power is derived from generator, transformer,
or converter windings and has no direct electrical connection, including a solidly
connected grounded circuit conductor, to supply conductors originating in another
system, if required to be grounded as in Article 250-5(a) or (b), shall be grounded as
specified in Section 250-26.
4. UPS classification: Digital’s UPS inverter is connected to an isolation transformer,
where its secondary windings are connected in WYE configuration. The UPS requires
the bypass ac input to be fed from a WYE-connected source. The neutral of this
source is directly connected to the neutral of the output isolation transformer. So,
the UPS may or may not be considered a separately derived source, depending on the
arrangement of the bypass ac input neutral.
5. Specific provision: The NEC prohibits connecting the grounded circuit conductor
(neutral) to the grounding conductor at more than one point. The reason is that if
the neutral were connected to the grounding conductor at more than one point, some
of the neutral current would be allowed to flow in the grounding conductor circuit
between the points of connection. Besides being a safety hazard, this practice defeats
ground fault protection schemes.

Nominal value ±1% for all conditions of line, load, and temperature

Frequency:

Normally synchronized to the bypass ac input source (when
available); otherwise, the output frequency is the nominal value
±0.1%

Phases:

Three-phase, phase rotation A, B, C

Wires:

Three or four. The UPS inverter output is normally a Wye
configuration with the neutral grounded. A three-wire delta load can
be connected to the UPS inverter output, but the phase connections
cannot be grounded.

Current:

See Table B–2

Power Factor:

The UPS inverter output is rated at full kVA, 0.8 power factor lagging
load

Slew Rate:

The rate of change of the UPS inverter output frequency, while
tracking within the frequency window, when synchronizing to the
bypass ac input source, or when going to a free-running condition
after losing ac input power, is 1 Hz/second maximum

Overload
Characteristics:

Applies to the UPS output when operating from either the bypass ac
input source or the UPS inverter output:
125% for 10 minutes
150% for 1 minute
Overloads in excess of 150% or exceeding the overload time periods
previously indicated, will cause the load to be transferred from the
UPS inverter output to the bypass ac input source, provided the
sources are synchronized. Once the load is transferred to the bypass
ac input source after exceeding the time periods previously indicated,
the timed periods will start again for operation on the UPS static
switch. If the load does not return to less than the unit’s fill load
rating prior to completing the timed overload periods, the load will be
disconnected.

Dynamic
Characteristics:

Peak voltage deviation on the UPS inverter output is listed below for
the conditions indicated:
50% step load change ±3% maximum
100% step load change ±5% maximum

Dynamic Response:

The UPS inverter output voltage returns to ±1% of nominal within
one cycle after experiencing a 100% step load change

Battery Characteristics
DC Voltage Range:

325 Vdc minimum
436 Vdc maximum

DC Current Required:

See Table B–2

SPECIFICATIONS B–3

Environmental Characteristics
Temperature:
•

Operating Range:

0° to 40°C (32° to 104°F), excluding battery

•

Storage:

-25° to 70°C (-13° to 158°F)

NOTE
Batteries should be stored only in a fully charged condition at temperatures not
exceeding 25°C (77°F). Storage at higher temperatures will reduce storage life and may
reduce battery life.
Relative Humidity:

0 to 95%, noncondensing

Recommended
Environment:

Computer room or other temperature-controlled environment

Recommended
Temperature:

20° to 30°C (68° to 86°F)
Battery protection time is based on a 25°C (77°F) ambient
temperature

Recommended
Relative Humidity:

50%
