STEP 1 Unpacking and Positioning
This section describes installation of the Galaxy 3000 10-30 kVA UPS, including receiving, handling, and storage
procedures; prerequisites to the installation; installation procedures; and start-up procedures.
Once the Galaxy 3000 UPS System has been inspected and received from the shipping courier, the unit should be
moved with the
use of a fork lift or pallet jack to a position as close to the final installation location as possible.
Figure QS-1: Pallet Mounting Configuration for the Galaxy 3000.
Installation should be performed by a qualified electrician and should conform to local and national
electrical codes.
Prior to any installation, the following items should be observed upon receipt of the Galaxy 3000 10-30 kVA UPS.
The casters on the unit will allow it to be positioned into the final installation location. At this point, the leveling legs
can be adjusted to provide a level and stable footing for the Galaxy 3000 UPS system. See Figure QS-1.
1) Inspect shipment for any damage prior to receipt. Damage claims should be filed directly with the courier.
Replacements for damaged components should be ordered through MGE Customer Support Services at 1-800-
438-7373.
2) Move equipment as close to the final location as possible using a pallet jack or forklift.
3) Once equipment is close to the installation location, and If configuration is optional pallet mount, remove the
Galaxy 3000 UPS from the shipping pallet using extreme caution when rolling the cabinet off the pallet as its
weight may exceed 500 lbs. See Figure QS-1.
4) All cabinets are equipped with casters allowing the equipment to be placed into final position. Push cabinets
very slowly into position to avoid any tipping hazard.
5) Once in position, adjust the leveling legs to provide a fixed and stable footing for the Galaxy 3000 UPS system.

Installation and User Manual
STEP 2 Connect the Main Utility Power
All Galaxy 3000 UPS systems provide the option for dual (redundant) utility power inputs. Whether the single or
dual inputs are selected, the connection of the utility feed is made to the same terminal block strip in the Galaxy
3000 UPS system.
From the diagram Figure QS-2 below, it can be seen that the main power feed to the Galaxy 3000 system should
be connected to the terminal blocks TB1 on the
right hand side of the strip. If a bypass AC source is available (and
the unit was specified to include a second AC source), this power should be connected
to the middle set of terminal
blocks TB3.
If the Galaxy 3000 system was specified for a second (bypass) AC source, but a separate power source is not
available, then jumpers should be installed from the primary AC source to the terminal blocks for the bypass AC
source.
NOTE The three phase power should be supplied as a Wye with a separate
neutral that will be connected to the input neutral busbar.
If the second (bypass) AC source if provided from a source other than
that of the main input, it is recommended to use isolation transformers
so that the neutral of both AC sources can be grounded to the same
potential.

Quick Start Notes
If AC power is required on site prior to the arrival of the MGE Field Engineer, the following procedure will provide
the AC power without powering the UPS. Any questions about this procedure contact the MGE Field Service
support line at 800 438-7373.
A. Insure that the Bypass Switch is in the BYPASS position.
B. Insure that the battery breaker, QF1, is open.
C. Close the input power breaker to energize the AC power.
D.
At this point, power will be available for site usage until the UPS is properly commissioned.
E. Upon arrival of the MGE Field Service Engineer, the main power must be disconnected so that a safe and
proper commissioning of the unit may be accomplished.
WARNING Do not, under any circumstance, rotate the switch to the TRANSFER or
NORMAL position, or close the battery breaker, QF1, until the unit has
been commissioned by an MGE Field Engineer.

Introduction
1.0 Scope
Provides a general description of the Galaxy 3000 systems intended use, major components, and environmental
and mechanical specifications.
1.1 General Description
The Galaxy 3000 is the world’s first data center grade Uninterruptible Power Supply system designed specifically for
mid-range enterprise level applications. The Galaxy 3000 family consists of units available in power ratings from 10 -
30
kVA, and are optimized for compatibility with nonlinear computer-type loads.
By incorporating the Ultra High Availability Topology (UHAT), the Galaxy 3000 family of UPS systems are designed
to provide the optimal level of reliability and to react to any power disturbance in an inherently safe way to protect
the critical load. The Galaxy 3000 all-in-one design incorporates every feature into one compact cabinet, including
a graphical user interface, power factor corrected input, batteries, and communication cards that support network
based power management.
The Galaxy 3000 UPS and its auxiliary equipment are designed for installation in a room where humidity and temper-
ature can be controlled. The recommended and maximum environmental parameters are listed in Appendix A,
Specifications, of this document.
The Galaxy 3000 UPS and auxiliary equipment is listed for safety by Underwriters Laboratories, Inc. (UL) under UL
Standard 1778 - Uninterruptible Power Systems; and also listed by Underwriters Laboratories (CUL) under
Canadian Standards Association (CSA) standard C22.107.

86-172010-00 C05 Introduction

1.1.1 Major Components
Rectifier Converts AC input voltage to DC voltage. The rectifier uses IGBT (Insulated
Gate Bipolar Transistor) power transistors and a Pulse Width Modulated (PWM)
technique to provide input power factor correction and to minimize any harmonic
reflected onto the input power lines.
Inverter Converts DC voltage from the rectifier or from the batteries into AC output voltage
to maintain the attached load. This module uses the IGBT technology to provide
digital power quality.
Static Switch Automatically supplies the attached load from the bypass source when the inverter
is off.
Battery System Stores energy for utilization by the inverter and attached load in the event that utility
AC power is lost or is of unacceptable quality.
1.1.2 Galaxy 3000 Micro and Standard Cabinets
The Galaxy 3000 UPS system is available in two different cabinet sizes, the Micro cabinet and the Standard cabinet.
Dimensions for the cabinets
are:
◗Micro cabinet: 48.6in (1234.4) H x 23.0in (584.2) W x 38.1in (967.7) D
◗Standard cabinet: 62.5in (1587.5) H x 32.8in (833.12) W x 40.1in (1018.5) D
Both cabinets are designed to provide for top and bottom entry of the utility power feed. The Micro cabinet is
typically supplied assuming bottom entry only.
Operating internally on 208 VAC, the Galaxy 3000 UPS system can be purchased to accept 208 VAC, 220 VAC,
480 VAC, or 600 VAC utility feed with the use of an internal input transformer contained in a Standard cabinet. The
Micro cabinet was designed to provide all of the features of the Galaxy 3000 system in the smallest possible
enclosure. Without an auxiliary cabinet, the Galaxy 3000 system in a Micro cabinet provides only 208 VAC input
and 208 VAC output.
An output voltage of 208 VAC is standard with the Galaxy 3000 and does not require any additional cabinetry. If
output voltages of 240 VAC, 408 VAC or 600 VAC are required, an auxiliary cabinet is required for the output
transformer.
The complete list of additional cabinets that could be included with your Galaxy 3000 system are: External
Maintenance Bypass cabinet, extended battery cabinet, and distribution cabinets.
1.1.3 Preparation for Operation
Several items must be considered when preparing the Galaxy 3000 UPS system for operation.
First – The UPS cabinet and its auxiliary cabinets must be arranged in the required configuration to insure that the
interconnection cables are located in the correct adjacent cabinets.
Second – The cabinets must be in a location that provides for proper air flow and heat rejection.
Third – The room in which the Galaxy 3000 UPS system is located must maintain environmental conditions within
recommended tolerances
Forth – All electrical connections must utilize the top or bottom conduit entries provided.
The following sections discuss in more detail these items.
