HA3000 Power System Installation Manual

This document is the Installation Manual for the Digital Equipment Corporation HA3000 series (20-80 kVA) Uninterruptible Power System (UPS), published in November 1991.

It serves as a comprehensive guide for customers (site preparation), customer's electricians (installation), and Digital Services Engineers (pre-startup checks). The manual emphasizes that installation must be fully completed before Digital Services is called for startup, and includes warnings about hazardous voltages.

Key contents include:

• Checklists of responsibilities for all parties involved in site preparation, delivery, handling, and initial startup.
• Detailed site preparation information, covering environmental conditions (temperature, humidity), physical size, weight, floor loading, placement, and required clearances for the main UPS cabinet and all auxiliary components (battery cabinets, auxiliary cabinets, CSA cabinets, distribution cabinets).
• Procedures for receiving and handling the UPS equipment, including unpacking, moving, and caster removal.
• Step-by-step installation instructions for electrical connections (AC inputs, battery, control wires, output loads) for the HA32A UPS cabinet and its various optional auxiliary cabinets (HA32B, HA32C/D/E, HA33D/F, HA32J/K), as well as remote panels and detectors (HA320-AA/AB, HA320-A3, HA320-C2, HA320-B1).
• An appendix on electrical considerations, including terms and definitions related to grounding and power sources, and detailed specifications (electrical ratings, dimensions, weights) for all HA3000 series components.
