MGE UPS SYSTEMS - Galaxy 3000 Specification 3 Effective: September, 2006
1.9 SERVICE AND SPARE PARTS
The manufacturer shall, upon request, provide spare parts kits for the UPS module in a timely manner; as well
as provide access to qualified factory trained first party service personnel to provide preventative maintenance
and service on the UPS module when required.
1.10 MAINTENANCE, ACCESSIBILITY AND SELF DIAGNOSTICS
All UPS subassemblies, as well as the battery, shall be accessible from the front. UPS design shall provide
maximum reliability and minimum MTTR (mean time to repair). To that end, the UPS shall be equipped
with a self-test function to verify correct system operation. The self-test function shall identify the
subassembly requiring repair in the event of a fault. The electronic UPS control and monitoring assembly
shall therefore be fully microprocessor based, thus doing away with all potentiometer settings. This shall
allow:
n Auto-compensation of component drift;
n Self-adjustment of replaced subassemblies;
n Extensive acquisition of information vital for computer-aided diagnostics (local or remote);
n Socket connection to interface with computer-aided diagnostics system.
The UPS shall be repairable by replacing standard subassemblies requiring no adjustments.
Communication via a modem with a remote maintenance system shall be possible.
2.0 PRODUCT DESCRIPTION
2.1 APPROVED MANUFACTURERS & PRODUCT DESCRIPTION
A. Approved Manufacturer(s): The specified equipment will be manufactured by MGE UPS SYSTEMS or
approved manufacturer in compliance with specifications.
B. Product Description: This specification describes a three phase, double conversion, on-line, solid state
Uninterruptible Power System, hereafter referred to as the UPS. The UPS shall operate in conjunction
with the existing building electrical system to provide power conditioning, back-up power protection and
distribution for electronic equipment loads. The system shall consist of a solid state IGBT PWM inverter,
IGBT rectifier with a power factor corrected input, static switch, internal maintenance bypass switch,
battery plant, graphical status/control panel, dry contact and communications ports, and synchronizing
circuitry as described herein.
