Introduction

1.0 Scope

Provides a general description of the Galaxy 4000 systems intended use, major components, mechanical and
environmental specifications.

1.1 General Description

The Galaxy 4000 is the world’s first data center grade Uninterruptible Power Supply system designed specifically
for mid-range enterprise level applications. The Galaxy 4000 family consists of units available in power ratings from
40 - 75KVA, and are optimized for compatibility with nonlinear computer-type loads.

By incorporating the Ultra High Availability Topology (UHAT), the Galaxy 4000 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 4000 all-in-one design incorporates every feature into one compact cabinet, including
a graphical user interface, power factor corrected input, and communication cards that support network based
power management.

The Galaxy 4000 UPS and its auxiliary equipment are designed for installation in a room where humidity and
temperature can be controlled.

The Galaxy 4000 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.

1.2 Major Components

Rectifier Converts AC input voltage to DC voltage. The rectifier uses IGBT (Insulated G a t e

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.

1.3 Single Line Diagram

During normal operation, the utility power (Main input) is supplied to the UPS rectifier. The rectifier converts the AC
power to DC that is supplied to the inverter. The inverter converts the DC voltage to three-phase regulated AC
voltage, which is supplied to the attached load.

During power failure conditions, the inverter is supplied by the stored energy in the battery system, and the load is
powered continuously with no interruption.

The Galaxy 4000 UPS is designed for internal operation of 208VAC input and output. External batteries, and an
output distribution panel may be contained in auxiliary cabinets similar in design to the Galaxy 4000 cabinet.
Batteries or external maintenance bypass circuit breakers may also be contained in third party cabinets or wall
mounted units.

cabinet, external battery cabinet, and distribution cabinet.

The external battery cabinets are provided in two different cabinet sizes depending upon the battery type selected.
Up to four battery cabinets may be provided. The cabinets may be installed adjacent to the UPS or remotely and
are designed for top and bottom entry. The distribution cabinet provides a 42 pole panelboard, with an optional
submain circuit breaker. The cabinet is designed for top and bottom entry.

1.5 Preparation for Operation

Several items must be considered when preparing the Galaxy 4000 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 4000 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 these items in more detail.

1.6 Cabinet Placement

The complete UPS system may consist of one to three cabinets depending on the options selected. The UPS
cabinet allows system options to be selected based on the application. When facing the Galaxy 4000 UPS from the
front, the standard arrangement provides for any external batteries to be located on the right hand side, and the
distribution cabinet to be located on the left hand side of the UPS. Refer to Figure 1-3 for cabinet placement.

1.7 Heat Rejection and Air Flow

The 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. To assist you in planning for
your HVAC needs, heat rejection data is provided in Table 1-1. The cabinet airflow and recommended top clearance
are provided in Figure 1-3. The Galaxy 4000 is intended for use in an environment where control of temperature
and humidity is provided.

3.4 Measurements

Selecting the Measurements option from the main menu
provides the following screen selections: battery, power,
current, voltage, frequency measurements, and ratios.

3.4.1 Battery Measurements Screen

The Battery Measurements screen provides a rapid
assessment of the available battery voltage, current,
battery charge, temperature as well as expected service
life. See Figure 3-6.

The backup time measurement will be calculated if the
following battery parameter identification (BPI) require­ments are met:

Required Conditions to Initiate BPI:

◗ BPI set to automatic in personalization.

◗ Battery charge level = 100%.

◗ UPS On-line (Inverter Coupled).

◗ Mains 2 within tolerance.

◗ Percent load is >15%.

◗ Battery temperature 0-40°C (32-104°F).

◗ No battery faults.

◗ No rectifier or inverter overload condition.

If the above conditions are met and maintained then the UPS will run a successful BPI. A normal BPI will drain the
batteries to a level of 80% capacity. When the BPI is completed successfully, the backup time will be displayed when
the batteries are 100% charged. If the load does not change by more than ±20%, then a BPI will be run again in one
year. Another BPI will run only if, the load changes by ±20% or the BPI is a year old.

If one of the conditions below occurs during the performance of the BPI, the BPI will be aborted.

Factors Leading to Abort a BPI:

◗ Inverter to mains 2 source transfer.

◗ Load percent drops to <15%.

◗ Battery temperature outside 0-40°C (32-104°F).

◗ Percent load changes more than +/-5% from starting power level.

◗ Communication fault.

◗ Input current 0 amps or > 100% load current.

◗ Rectifier or inverter overload.

◗ Mains 1 or Mains 2 failure.

In case the BPI cannot be done, a simplified autonometer will be used. This autonometer will start and display
backup time when the batteries are 100% charged. Because the calculation used is more simplified than the one
used for calculating backup time using a BPI, these will be less accurate. Therefore it is preferable to use the BPI
whenever possible. This provides an option for example, when less than 15% load or cannot run a BPI.

Operation

4.0 Scope

Provides startup, shutdown, and normal operation of the Galaxy 4000 UPS. Included are pre and post startup
safety checklists.

The Galaxy 4000 system is simple to operate and yet provides a wealth of continuous monitoring and diagnostic
features to ensure the proper operation. Operators gain access to information in the Galaxy 4000 system through
the display panel. See section 3 for operation of the display panel.

4.1 Preparing for Startup

Before being able to use the display panel to monitor and control your Galaxy 4000 system, a number of items
should be verified to insure that all conditions will provide for safe operation. The following check lists are provided
to aid in the successful pre and post startup of the Galaxy 4000. They include items to verify prior to applying power,
and then tests that should be performed (when appropriate) after startup to verify the health and functionality of all
critical modules within the system.

Before starting the Galaxy 4000, read this Installation and User Manual thoroughly. Be certain that you fully under­stand the operation of the indicators, controls, and operational sequences. MGE UPS SYSTEMS offers professional
startup services in most countries. It is strongly suggested that before applying power to your Galaxy 4000, you
contact MGE Field Services to properly commission your system.

4.1.1 Pre-Startup Safety Check List

◗ Ensure all power and control wires have been properly connected and securely tightened.

◗ Check to see that the upstream and downstream protective devices are not tripped, and have been sized

properly for the UPS and load requirements.

◗ Check that the input voltage is the same as indicated on the UPS nameplate, located inside the door of the

Galaxy 4000 UPS.

◗ Make certain that nothing is blocking the air intake underneath and around the front bottom of the UPS and

that the air exhaust on the top of the UPS is free of all obstructions.

◗ If present, check to see that the external optional maintenance bypass circuit breakers CB1, CB2, and CB3

(optional breaker) are in the OFF (open) position.

◗ Check to see that the battery disconnect circuit breaker(s) CB1 (in battery cabinet) is in the OFF

(open) position.

◗ Check to see that the cabinet is resting on its lifting leveler jacks and are not on the 4 casters.

◗ Check that the load-circuit breakers (where applicable) are in the OFF position.

Installation and User Manual

4.2 Normal Startup Procedure

With all of the initial safety check lists verified, the Galaxy 4000 UPS system can now be powered.

The following startup procedure should be performed during the initial startup following installation and commis­sioning of the system (typically by a MGE Field Engineer), and this sequence should be followed any time that the
Galaxy 4000 UPS is being restarted from an off condition (i.e., after the UPS has been powered down by removing
the upstream AC input power and opening all the circuit breakers of the UPS). For device locations refer to Figure 4-1.

a. Apply power to the UPS bypass by closing the upstream circuit breaker supplying Q4S (mains 2).

b. Apply power to the UPS input by closing the upstream circuit breaker supplying the main AC input Q1 (mains 1).

c. Close the maintenance bypass switch Q3BP in the UPS cabinet or in an external cabinet if present. Power is

now available at the UPS output (the load is energized) via maintenance bypass.

d. Close the bypass switch Q4S. The static switch will come on-line; the fans will start and the display will illuminate.

e. Close the output isolation circuit breaker Q5N.

f. Open the maintenance bypass switch Q3BP in the UPS cabinet or in an external cabinet if present. The load is

now supplied via the static bypass.

NOTE

If your UPS configuration does not include the maintenance bypass option,
startup requires only closing Q4S and Q5N to supply the bypass source to the
attached load.

IMPORTANT If the UPS is programmed for automatic restart the inverter will automatically start.

g. Close the input switch Q1. Verify that the following conditions exist:

– The red “load not protected” LED is on.
– The rectifier automatically starts.

If either condition is not present, there is a fault. Open Q1 and contact MGE Field Services.

h. Close the battery disconnect circuit breakers CB1. The batteries are now connected to the battery charger, and

have begun charging.

i. If the UPS is programmed for manual restart, press the “inverter on” green pushbutton.

j. The UPS will automatically transfer the load to the UPS inverter output. The green “load protected” LED will turn

on and remain on.

k. Close the optional output distribution circuit breakers (if present).

NOTE If the transfer conditions are not satisfied (bypass AC input source is out of

tolerance, or some other reason), a forced transfer is required.

Operation 4 — 386-173010-00 A00

4.3 Post Startup Safety Check List

After initial startup of the system, normal operation should be tested. At the minimum, the following tests should be
performed as applicable to your installation.

◗ Emergency Power Off (EPO) test.

◗ Remote Emergency Power Off (REPO) test (if applicable).

◗ Inverter start and stop.

◗ Battery transfer test.

◗ Maintenance bypass procedure.

CAUTION As soon as AC input power is supplied to the Galaxy 4000 (customer supplied

upstream circuit breaker is in the "ON" position), the load is initially supplied via
the "Static Switch". Verify that no error indications are present on the operator
interface display panel.

4.4 Shutdown Procedure

Proceed as follows:

1. Press the gray, Inverter OFF button.

2. Confirm by pressing the function key.

The load is no longer protected by the UPS. It is supplied via the bypass.

3. Set the battery circuit breakers CB1 (in battery cabinet) to the OFF position.

4. Close Q3BP, open input switch Q1, bypass switch Q4S, and output breaker Q5N.

5. To completely remove power from the UPS, open Q3BP and open the upstream circuit breakers supplying AC
power to switches Q1 and Q4S. Attention: There is no power to the load.

4.5 Shutdown Using EPO

During an emergency situation the UPS and all downstream devices can be instantly shutdown by pressing the red
emergency power off (EPO) pushbutton on the front door of the UPS cabinet, or pressing the remote emergency
power off (REPO) pushbutton (if applicable) located within the room.

IMPORTANT Pressing the EPO button disconnects the attached load. The emergency power off

(EPO) is to be used during emergency situations only, where a hazard to
personnel or equipment exists.

4.6 Recovery from EPO

To recover from an emergency power off press the EPO pushbutton again. Follow the normal startup procedure in
Section 4.2.

NOTE The EPO pushbutton is a latching device. The EPO condition will remain until the

EPO button is depressed a second time.
