Safety Safety Instructions This manual contains important instructions for MGE Galaxy 4000 that must be followed during operation and maintenance of the equipment. W ARNING: Opening enclosur es expose hazardous voltages. Always r efer service to qualied personnel only .
Safety of Persons • The UPS has its own internal power source (the battery). Consequently , the power terminals may be ener gized even if the UPS is disconnected from the AC power source. • The UPS must be properly grounded. • The battery supplied with the UPS contains small amounts of toxic materials.
Specications Environmental Recommendations Recommended Environment 20° to 25°C (68° to 77°F .); 50% relative humidity; computer room or other temperature, and humidity-controlled environment Op.
Mechanical Assembly General Description The MGE Galaxy 4000 is the world’ s rst data center grade Uninterruptible Power Supply system designed specically for mid-range enterprise level applications.
Major Components Rectier Converts AC input voltage to DC voltage. The rectier uses IGBT (Insulated Gate Bipolar T ransistor) power transistors and a Pulse W idth Modulated (PWM) technique to provide input power factor correction and to minimize any harmonic reected onto the input power lines.
Preparation for Operation Several items must be considered when preparing the MGE Galaxy 4000 UPS system for operation. 1. The UPS cabinet and its auxiliary cabinets must be arranged in the required conguration to insure that the interconnection cables are located in the correct adjacent cabinets.
Heat Rejection The MGE Galaxy 4000 UPS cabinets generate heat and exhaust air through the top portion of its enclosures. Air intake is through the bottom and front of the cabinet. All other cabinets are convection cooled. T o assist you in planning for your HV AC needs, heat rejection data is provided in table below .
Prepare the Installation Conduit Plate Locations for Bottom Entry Cable entry through the bottom is the standard preferred design for the MGE Galaxy 4000 UPS cabinet. The bottom entry conduit plate provides space for up to ve (5) separate conduit entries.
Conduit Plate Locations for T op Entry The UPS cabinet for the MGE Galaxy 4000 is capable of accepting power input and output cables through a top entry . The conduit plate on the top of the cabinet provides provisions for knockouts for conduit and is secured to the cabinet with screws.
Connect AC Input and Power Cables Installation Steps APC r ecommends corr ect installation verication and unit startup to be performed by an APC certied Service partner . Caution: Scheduling of the APC certied Service partner typically should be done 7 to 10 days before they are required on-site.

UPS Connections Electrical connections and cabinet interconnection will vary depending upon the conguration and options selected with your MGE Galaxy 4000 UPS system.
Connect Battery Cables Battery Connections The connections to be made are the positive, negative, and ground cables from the battery cabinet to the UPS. The battery cables are terminated at the positive, negative, and ground busbars. See “T ypical Power Connections“ .
Connect AC Output AC Output Connections The connections to be made are the three phases, neutral, and ground cables from the load to the UPS. The output cables are terminated at the output terminal block (TB2).
Connect Remote Emergency Power Off Remote Emergency Power Off Connections The control connections are available for Remote Emergency Power Of f (REPO) through a customer-supplied (normally closed) pushbutton. W ith REPO connected, the jumper on the REPO terminal blocks must be removed.
Connect Relay Communication Card Relay Communication Card Contacts The relay communication card contains six programmable dry contact outputs and two programmable dry inputs and is standard on the MGE Galaxy 4000. The inputs and outputs are factory programmed according to functions listed in table below .
