1.2 General Description

The cabinets are cooled by forced ventilation. The air enters via the doors and grids at the bottom and is discharged
through the roof, which means the cabinets can be positioned against the back wall.

Connections are made through the bottom. (Connections through the top are an available option.)

The connection cables may be run in three ways:

◗ In a trench running under the cabinets.

◗ Under a false floor.

◗ On the floor under the cabinets, in the free space equal to the height of the feet; in this case the cables

should be run side by side to avoid blocking the flow of air for ventilation.

The cables for connections are between:

◗ The battery and UPS cabinets (power and control cables).

◗ The bypass AC-source transformer in an auxiliary cabinet and the UPS cabinet.

Only the wires for the inter cabinet control connections between parallel-connected UPS units are supplied.

The other power cables for connections between cabinets are not supplied.

Installation and User Manual

1.3 System Major Power Components

Rectifier/charger module (A) Converts 3-phase AC power from the normal AC source supply (1) into DC power

for the normal inverter input and float charges or recharges the battery.

Battery unit (D) Provides backup power for the inverter in the event of a voltage drop or a normal AC

source failure.

Inverter module (B) Converts the DC power supplied by the rectifier/charger module or the battery unit

into 3-phase AC power for the load.

Static bypass module (C) Ensures the instantaneous transfer of the load to the bypass AC source input in the

event of an inverter shutdown (initiated by the user or by a protective device) or a
sudden overload.

Maintenance Bypass Isolates the UPS for maintenance and transfers the load to bypass AC source input

without interrupting the supply of power. The maintenance bypass is made up of
three manual switches (Q3BP, Q4S and Q5N).

External Bypass Option for parallel UPSs and Hot-Swapping.

Q5N: Isolation of the inverters of all the parallel UPS systems from the load.

Q3BP: Bypass for maintenance.

The normal AC input and the bypass AC input have different functions and, depending on the installation, may be
protected differently upstream and/or come from different sources.

When increased power is required, several Galaxy PW™ units may be connected in parallel (up to four, refer to
section 4.0). In this configuration, an "isolation" function is added for the UPS system as a whole for maintenance
purposes, without interrupting the supply of power to the load.

1.4 Different Types of Galaxy PW™ Systems

1.4.1 Single UPS System

Figure 1-2: Galaxy PW™ Single UPS System.

Note: *The Fuse is to protect against catastrophic rectifier/inverter semiconductor failure.

1.4.2 Parallel UPS System

Parallel UPSs can be utilized when increased power is required (two to four parallel units), or an external bypass
must be added.

CAUTION PARALLEL UPS WITH EXTERNAL MAINTENANCE BYPASS During mainte-

nance operation, when CB1 (MBP) is closed and CB2 (UPS ISOLATION) is
open, each UPS control panel display will show a message “LOAD
PROTECTED” when the UPS is placed in ON-LINE MODE. In this mode the
critical load is not protected because it is supplied by the maintenance
bypass power.

1.6 Electrical Parameters for Selecting Protective Devices

1.6.1 Normal AC Source

The parameters given in Table 1-1 can be used to determine the required rating of the upstream protective circuit
breaker on the normal AC input for one single-UPS or parallel-UPS unit.

Normal and Bypass AC Input:

number of conductors 3 phases

rated voltage and tolerances 480 V ± 10% (adjustable to ± 15%)

rated frequency and tolerances 60 Hz / ± 10%

IMPORTANT It is essential to choose the type of circuit breaker according to its breaking

capacity and the prospective short-circuit current at its place of installation.
This choice must also be made so as to protect the static-switch semicon­ductors with respect to the maximum permissible currents and ensure
discrimination between the UPS output fuses and the downstream
protection devices.

Table 1-1: Electrical Parameters for Normal AC Source.

Electrical parameters for the normal AC source

200 328 316 395 474
225 332 320 400 480

(1) The rated normal AC source currents (In) have been determined for a rated phase-to-phase voltage of 480 V,

a battery with a 10 minute backup time at the beginning of its charge (412 x 1, 2 = 494 Volts) and full rated load
with a power factor of 0.9.

(2) The rated normal AC source currents (In) have been determined for float charging voltage and full rated load

with a power factor of 0.9

(3) The normal AC source currents given for an overload of 25% or 50% are maximum values. They have been

determined for a battery with float charging voltage and a load power factor of 0.9. When choosing the circuit
breaker rating, use the "rated current" column and check that the circuit breaker tripping curves are compatible
with the values in the overload columns.

System Setup

2.0 Scope

System Setup describes receiving and handling of the Galaxy PW™ 100 to 225kVA, a description of major compo­nents, the battery cabinet, and definition of the control panel indicators, which includes electrical, mechanical and
environmental specifications.

MGE also recommends obtaining an MGE field service engineer for final installation and basic startup for single and
parallel units.

CAUTION Scheduling of the MGE Field Service Engineers typically should be done 7 to

10 days before they are required on-site. If the startup of the UPS is critical
to maintaining your schedule, please call the MGE toll free telephone number
at

1-800-438-7373 for assistance.

The MGE Field Service Engineers will

insure a

quick installation for the initial safe startup and configuration of your Galaxy PW™.

Final installation and start-up should be completed by a qualified MGE Field Service Engineer.

2.0.1 First steps by an on-site qualified Technical Engineer

Step 1. Unpack and position the unit.

Step 2. Connect the main (utility) power.

Step 3. Connect the power circuits.

2.0.2 Final steps by MGE Field Service Engineer

Step 4. Call MGE and wait for the MGE Field Service Engineer to complete the installation.

Step 5. The MGE Field Service Engineer finalizes installation and the startup process.

Optional: Procedure for temporary power prior to the final startup.

2.0.3 Required Equipment and Tools

The following equipment and tools are recommended for on-site installation:

◗ Digital volt meter (DVM)

◗ 1/8 inch slotted screwdriver

◗ Pallet jack/forklift

◗ Conduit installation tools

◗ Nut driver set

2 — 186-133060-00 A00 System Setup

2.1 Receiving

On delivery, check that the equipment has not been damaged in transport (declare any damage to the carrier in
accordance with customary claim procedures).

Also check that the characteristics noted in the test report for the equipment correspond to those specified on the
order form. In the event of a non-conforming item, quote the delivery note reference number when making your
claim.

2.1.1 Handling

The cabinets are delivered on pallets, equipped with a shock absorbing system. Ideally, the equipment should be
unpacked just before installation (see "unpacking" section below). Cabinet weights and dimensions are specified on
the packaging. Cabinets may be handled in one of the following ways (see Figure 2-1):

Rolling on Bars (B)

Do not mount the foot pads, but place the cabinet on the rollers (at least three). The cabinet may be pulled on rollers
using a sling positioned horizontally. This technique should only be used when absolutely necessary (narrow
doorway or corridor, preventing the use of a fork-lift or pallet-mover).

From the Bottom (A)

The cabinets can be moved from the front or the rear (715 mm wide cabinets) using a pallet truck or fork-lift truck,
or on the 4 surfaces (1015 mm and 1215 mm wide cabinets) using a fork-lift truck.

Fork tunnel height: 140 ±10 mm.

Fork opening: 560, 650 or 700 mm according to cabinets width.

The 715 mm wide cabinets are designed to pass through 715 mm wide openings, and the other cabinets are
designed to pass through 825 mm wide openings. For narrow openings, (follow the instructions below) cabinets are
normally 825 mm deep.

This depth can be reduced to:

◗ 817 mm by removing rear panels.

◗ 805 mm by removing doors.

◗ 800 mm by removing doors and door hinges.

unpack the cabinet, refer to section 2.2 ‘Unpacking’, page 4. The cabinet can then be handled by lifting machines
on all surfaces after the pallets have been dismantled by removing the rear panels, and remove the fixing screws
using a "torx" screwdriver.

Removing the doors:

1. Open the door(s).

2. Disconnect the door earth connection from the frame.

3. For cabinets fitted with a control panel, carefully disconnect the ribbon cables from the panel circuit boards
located on the inside of the door.

4. Knock out the hinge pins from below.

5. Remove the door(s).

Removing the door hinges:

1. Remove the screws holding the side panels to the hinges.

2. Remove the central screw holding the hinge.

2.1.2 Storage

The equipment must be stored in a dry and well-aired location, sheltered from rain, water sprays or splashes and
all chemical agents. Storage in original packing is recommended, since this packaging is designed to provide
maximum protection during storage and handling. If the unit must be unpacked prior to final installation, cover the
equipment with a shroud providing protection against dust, debris, or paint.

Please dispose of the packaging in accordance with the applicable legislation.

IMPORTANT Transport: the temperatures must remain within the -30° to +50°C range and the

duration should not exceed 30 days.

Storage: the battery is of the sealed lead-acid or vented lead-acid type and should not be stored for more than six
months at 20°C without recharging for batteries that are initially fully charged (for partially charged batteries, the
storage time should be reduced). After the recommended maximum storage time, the battery must be charged,
requiring partial start-up of the equipment (rectifier-charger).

The battery cells can be stored at a temperature between -20°C and +45°C if delivered in their initial packing.

The ideal battery storage temperature is between 15° and 25°C (higher temperatures result in reduced storage life
or downgraded technical characteristics). If higher temperatures cannot be avoided during transport or storage,
please consult us.

Installation and User Manual

3.6 Environmental Signal of the Media Contacts 11 Board

Terminals XR2, XR3, XR4 and XR5 on the "Media Contacts 11" board of each type of unit can be used to receive
signals from the operating environment and to transmit signals concerning the operating status of the UPS, see
Figure 2-3, page 2—5 for the position of the board, item 1 and 2).

3.6.1 Signal Reception

The signals should be provided by volt-free contacts.

Emergency off: An NC contact causes shutdown of the inverter and the rectifier/charger, opening of

the battery circuit breaker, blocking of the static bypass and activation of a relay
contact on the "Media Contacts 11" board.

Battery room
ventilation fault: A ‘NO’ contact causes shutdown of the rectifier/charger.

Battery circuit
breaker QF1 closed: A ‘NO’ contact prevents inverter start-up if the circuit breaker is open.

Battery temperature: A PC-board, placed near the battery, supplies information on the battery tempera-

ture, thus enabling the rectifier/charger to regulate the battery voltage.

"Auxiliary" signals: Depending on the selected settings, these signals may be used to provoke:

- forced shutdown of the inverter (whatever the status of the bypass AC source),

- protected shutdown of the inverter (load transfer to the bypass AC source).

- limiting of the current drawn by the rectifier/charger (programmable value) when
supplied by an engine generator set with an insufficient power rating. The additional
power required by the inverter is supplied by the battery which discharges,

- limiting of the battery charge current (programmable value) if the normal AC source
is replaced by an engine generator set with an insufficient power rating.

3.6.2 Signal Transmission

An auxiliary 24 V
power supply: Isolated and backed up, is used to supply:

- the undervoltage release of the battery circuit breaker(s) QF1.

- the board that measures the temperature in the battery room.

"low battery"
warning signal: (Volt-free changeover contact) indicating that battery time is about to run out.

The warning threshold may be personalized.

"load on UPS" signal: (Volt-free changeover contact) indicating that the load is supplied by the

inverter. For a single-UPS unit, one volt-free changeover contact may be used
to indicate that the load is supplied by the bypass AC source.

Installation 3 — 786-133060-00 A00

"load on battery power" signal: (Volt-free changeover contact) indicating that the inverter is supplied

by the battery in the following cases:

- normal AC source outage or voltage drop.

- rectifier/charger shutdown.

- rectifier/charger current limiting.

This signal, which may be used to initiate process saving and shutdown
procedures, is time-delayed 30 seconds to avoid unnecessary operations
following micro-breaks.

"Maintenance position" signal: (Volt-free changeover contact) indicating that:

- maintenance bypass switch Q3BP is closed,

- bypass AC source input switch Q4S is open,

- inverter output switch Q5N is open,

- battery circuit breaker QF1 is open.

Signal to open battery

circuit breaker(s) QF1: In the event the "emergency off" button is pressed or to avoid an excessive

battery discharge (lasting more than three times the rated backup time plus two
hours).

Repo Contact: (Volt-free changeover contact) used to trip switching devices in the event of an

emergency shutdown.

"General Alarm" information: (Volt-free changeover contact) which includes:

- internal faults.

- information on temperatures outside tolerances in the battery room (optional).

- overload information (> In).

- static-switch ventilation and power-supply faults.

NOTE The maximum breaking capacity of the changeover contacts is 5A at 250V.

3.7.1 Battery Circuit Breaker "QF1" Connection

Connect the cable from connector XR3 (pins 2 to 8) on the "Media Contacts 11" board in the UPS cabinet to
connector XR1 in the battery cabinet containing battery circuit breaker QF1.

IMPORTANT

In the case of a complex installation with parallel units, there should be only one
emergency shutdown pushbutton and this pushbutton must interrupt all the units.
This pushbutton must therefore have as many contacts as there are units in the
installation. The emergency shutdown pushbutton turns off the rectifier/ chargers
and inverters, opens the battery circuit breakers (QF1), the input circuit breaker (Q1)
on the normal source, the backfeed protection contactor (K4S) on the bypass AC
source, blocks the static switches and activates a contact on the "Media Contacts 11"
board (terminals 1 to 3 on connector XR4).

3.8 Installation of the "Temperature Monitor" in the Battery Cabinet

The "Temperature Monitor" unit is placed inside the battery cabinet housing circuit-breaker QF1. See Figure 3-9.

1. Open the unit cover, and before fixing, break the self-cleaving seal on the base of the unit for insertion of the
connecting cable.

2. Fix the unit on the plate using the self-adhesive sticker and a screw (nut and washer combination, diameter 4
mm, length 16 mm, not supplied).

3. Connect and put back the cover. The temperature sensor MUST be placed at the top of the cabinet to work
properly.

4. Tie the connecting cable to the cabinet upright so that it does not pull on the unit.

Operation

4.0 Scope

Operation describes the start-up for single and parallel units, modes of operation, normal specifications for operating
the Galaxy PW™ 100 to 225kVA, including display messages, measurement systems, alarms, batteries, and log
time stamping operations.

WARNING Rectifier/charger start-up is automatic when normal AC input circuit breaker Q1

is closed. DC voltage is present in the DC bus.

4.1 Start-up of a Module

Rectifier/charger start-up is automatic when the normal AC input circuit breaker Q1 is closed. The green
"rectifier/charger" light 1 on the control panel goes on. Close battery circuit breaker QF1.

Figure 4-1: Control Panel and Circuit Breaker Diagram.

Installation and User Manual

4.2 Operation in On-line Mode

4.2.1 Normal Operation

Normal AC source power is available, see Figure 4-5.

◗ Lights 1 , 4 and 5 shine green on the control panel.

-The power necessary for the load is provided by the normal AC source (1) through the rectifier/charger (A)
and the inverter (B). The rectifier/charger (A) also supplies the power to float charge and recharge the
battery if any.

The output voltage (DC) is regulated to supply:

◗ The float-charging or the recharging voltage for vented lead-acid or Ni/Cd batteries.

- a single charge voltage for sealed lead-acid batteries.

The voltages depend on the number of battery cells and the battery manufacturer. Factory set, they may also be
adjusted by support technicians.

An electronic board continuously measures the battery temperature and automatically adjusts the voltages.

NOTE In parallel Galaxy PW™ systems, the power drawn by the load is equally shared

between the different units.

4.2.2 Operation with the Normal AC Source Down

In the event of a normal AC source failure or voltage outside specified tolerances of ±10% in amplitude (±15%
optionally), the rectifier/charger (A) stops and the battery (D) supplies the necessary backup power to the load via
the inverter (B).

The battery, float-connected between the rectifier/charger and the inverter, discharges during this operating mode:

◗ lights 2 , 4 and 5 shine green.

The user is warned of battery operation by the slow beeping of the buzzer 6 , see Figure 4-6, and the message
"LOAD PROTECTED, BATTERY DISCHARGING", followed by the remaining backup time and the percent load.

This information is also available via volt-free changeover contacts for remote control devices.

Installation and User Manual

4.3 Operation with the Normal AC Source Restored

When normal AC source power (1) is restored or its voltage returns to within specified tolerances, the system
automatically returns to its normal operating mode described above (on the condition it did not reach the end of
battery power). If the end of battery power was reached (with the resulting inverter shutdown), the rectifier/charger
(A) restarts automatically, but the inverter (B) must be restarted manually.

The rectifier/charger recharges the battery (D) which was discharged during the mains outage. During battery
charging, light 2 flashes green.

The message "BATTERY CHARGING" is displayed, together with the value of the recharging current and battery voltage.

Figure 4-7: Normal Operation Mode Indicator Diagram.

The battery charge cycle takes place in two steps: See Figure 4-8.

step 1: the battery is recharged at a constant current limited to 0.1C10 (i.e. 1/10th of the battery capacity specified

for a 10 hour discharge). The DC voltage increases with the battery charge until the charge level is reached.

step 2: the battery is recharged at constant voltage equal to the charge level. The charging current gradually

decreases until reaching a specified low value (floating current).

For vented lead-acid batteries, the rectifier/charger supplies the charging voltage for 0 to 255 hours (parameter
defined by the after-sales support department) and then the floating voltage. For sealed lead-acid batteries, the
charging and floating voltages are the same.

NOTE

If the normal AC source failure is shorter than 0 to 255 seconds (default value = 30
seconds) (parameter defined by after-sales support department), the charger
automatically supplies the floating voltage given the low battery discharge.

4.4 Operation with Engine Generator Set

If a stand-by generator is included in the installation, it is generally started automatically in the event of a normal AC
source failure and connected to the main low voltage switchboard. It is disconnected when normal AC source power
is restored.

With such a system, the required battery time may be reduced to the time necessary for starting and bringing on
line the stand-by generator. The battery (D) supplies power to the inverter (B) during the transfers:

◗ Normal AC source to the generator.

◗ Generator to the normal AC source.

The transfer sequences described above (normal AC source ➜ battery, battery ➜ generator, generator ➜ battery,
and battery ➜ normal AC source) are fully automatic. They in no way affect the load and require no manual
operation by the user.

NOTE To avoid load surges on the generator, the rectifier/charger is started with a 10

second maximum current consumption walk-in (lasting 3 to 10 seconds,
depending on the percent load).

To avoid overloading an undersized engine generator set, it is possible to set a
maximum power level drawn by the normal AC input. Any additional power
required is supplied by the battery. This modification can be made on site by an
MGE UPS SYSTEMS field engineer

Installation and User Manual

4.5 Battery Time

The available battery time during a normal AC source outage depends on the:

◗ Rated capacity of the battery.

◗ Power consumed by the load.

◗ Temperature of the battery.

◗ Age of the battery.

The specified battery time corresponds to a minimum duration at full rated load.

The actual backup time can therefore be greater if the system operates below its full rated load during the normal
AC source outage. Operation on battery power can be extended beyond the specified time by reducing the load
power consumption (by disconnecting non-critical loads).

A "low battery" warning signal is sent via volt-free changeover contacts for remote control devices when the battery
voltage reaches a level slightly above the minimum level. This signal warns the user of the imminent end of battery
power. On the device itself, the buzzer beeps rapidly.

The message "LOW-BATTERY SHUTDOWN WARNING" is displayed, followed by the remaining backup time and
the percent load. Light 2 turns red and flashes.

Battery power stops when the voltage supplied by the battery reaches the minimum threshold. This results in
inverter shutdown and transfer of the load without interruption to the bypass AC source. Light 2 shines red (not
flashing). The message "LOAD NOT PROTECTED, ON-LINE MODE" is displayed and the buzzer sounds continuously.

If the bypass AC source also fails, the load is no longer supplied. The inverter automatically shuts down when the
time on battery power exceeds three times the specified backup time.

NOTE The "low battery shutdown" warning signal can be sent with an adjustable time

delay prior to the effective end of battery power.

Operation 4 — 786-133060-00 A00

4.6.1 Single UPS Unit (On-line mode)

In the event of a UPS shutdown (initiated by the user or by an internal protective device), the load is automatically
transferred to the bypass AC source. If transfer conditions are satisfied, transfer takes place instantly, without inter­ruption to the load.

NOTE Transfer conditions are not satisfied when bypass AC source characteristics are

outside tolerances (voltage: ±10%. frequency as per personalization. phase sync
with inverter ±3°).

In the event of a major transient overload (greater than 1.65 In), immediate transfer takes place as above, without
interruption to the load.

The return to the inverter is automatic when the overload disappears if the number of possible returns has not been
reached (0 to 255, programmable by personalization). If this number has been reached, the load continues to be
supplied by the bypass AC source. This operating mode allows start-up of load devices causing high inrush currents.

This system requires satisfied transfer conditions. If the conditions are not satisfied, the inverter will current limit to
165% of its rated current for 1 second before stopping.

In the event of a small but extended overload (i.e. a continuous level of power exceeding the full rated load), the
inverter will continue to supply power for a period depending on the magnitude of the overload (10 minutes for a
125% overload, 1 minute for a 150% overload). See the overload curve in Figure 4-11.

◗ In all the above cases, inverter shutdown and supply of the load via the bypass AC source results in the

following on the control panel:

- light 4 goes off,

- activation of the buzzer (continuous beep),

- light 3 shines green,

- the message "LOAD NOT PROTECTED, ON-LINE MODE" is displayed.

4.6.2 Parallel UPS Without Redundancy

WARNING During maintenance operation, when CB1 (MBP) is closed and CB2 (UPS

ISOLATION) is open, each UPS control panel display will show a message
“LOAD PROTECTED” when the UPS is placed in ON-LINE MODE. In this
mode the critical load is not protected because it is supplied by the mainte­nance bypass power.

Galaxy PW™ UPS 100 to 225kVA

Operation4 — 8 86-133060-00 A00

Installation and User Manual

The shutdown of one inverter results in overload on the other inverters in operation. Two cases may then arise:

A) if the overload on each remaining inverter is > than 1.65 in, the load is immediately transferred to the bypass

AC source.

B) if the overload is less than 1.65 in, the remaining inverters support the overload (see curve in Figure 4-11), and

the load is transferred to the bypass AC source.

After this transfer:

- the light 4 goes off,

- the buzzer is activated and sounds continuously,

- the light 3 goes on and turns green,

- the message "LOAD NOT PROTECTED, PARALLEL ON-LINE MODE" is displayed.

Figure 4-11: Overload Curve Diagram.

4.6.3 Parallel UPS With Redundancy

The shutdown of one UPS unit is of no consequence for the load. The others each take up an equal amount of load
power and the load continues to be supplied normally.

◗ Unit shutdown results in the following on the control panel:

- Lights 4 and 5 go off,

- Activation of the buzzer (continuous beep),

- The message "LOAD NOT PROTECTED, PARALLEL ON-LINE MODE" is displayed.

- In the event of an overload, the system only loses its redundancy as long as the overload is less than the
total rated power of the functioning units. If the overload is greater, the operating mode is that previously
described for systems without redundancy.

4.7 Output Voltage Quality and Continuity

The output voltage is stable in amplitude and frequency and is free of interruptions or transients outside specified
tolerances, irrespective of normal AC source or load disturbances (outages, load step changes, etc.).

4.7.1 Steady State Voltage Regulation

For stable or slowly varying load conditions, the inverter output voltage is regulated to within ±0.5% in amplitude.

The frequency of the output voltage can theoretically be regulated to within 0.1% of the rated value, however the
output frequency range may be intentionally extended to a maximum of ±2 Hz so that the inverter can remain
synchronized with the bypass AC source and its inherent frequency fluctuations, thus enabling transfer of the load
to the bypass line at any time.

When the bypass AC source frequency returns to within the specified tolerances, the inverter is gradually re­synchronized to the bypass line at a rate of 0.5 Hz to 2 Hz/s (as per the value personalized by the after-sales
support department), thus avoiding exposing the load to sudden frequency variations.

4.7.2 Transient Voltage Regulation

The inverter output voltage is not notably affected by instantaneous major variations in load characteristics.

This is made possible by the PWM (Pulse Width Modulation) chopping technique and the microprocessor-based
regulation system that instantly compensates for any variation. In particular, the inverter output voltage remains
within +/- 2% of the rated voltage for load step changes of 0 to 100% or of 100 to 0%.

The battery charge cycle takes place in two steps:

step 1: The battery is recharged at a constant current limited to 0.1C10 (i.e. 1/10th of the battery capacity specified

for a 10 hour discharge). The DC voltage increases with the battery charge until the charge level is reached.

step 2: The battery is recharged at constant voltage equal to the charge level. The charging current gradually

decreases until reaching a specified low value (floating current).

For vented lead-acid batteries, the rectifier/charger supplies the charging voltage for 0 to 255 hours (parameter
defined by the after-sales support department) and then the floating voltage. For sealed lead-acid batteries, the
charging and floating voltages are the same.

4.10 Alarms

The auto diagnostic system considers any system status other than normal as a problem.

Before taking any action, note down the messages displayed on the control panel.

Certain problems may prevent the control panel from functioning.

In this case, it is strongly recommended to call the MGE UPS SYSTEMS Customer Support Service

at:

1-800-438-7373

.

A) If the load is still correctly supplied with power, it has probably been transferred to the bypass AC source (static

bypass) and is therefore no longer protected (if the system is in on-line mode).

B) If the load is no longer supplied with power, transfer it manually to the maintenance bypass.

Figure 4-13: Display of Alarm Messages..

4.11 Maintenance Bypass Option

The Maintenance bypass option provides a direct bypass AC input source (mains 2) that can be used to supply the
critical load while the UPS is being serviced.

This operation is possible only if the system includes a bypass AC source. It results in the load being directly
supplied by the Bypass AC source via Maintenance Bypass switch Q3BP, thus ensuring a higher level of security in
the event of a malfunction.

Switching procedures are explained on drawings next to each switch in the UPS cabinet and the External Bypass unit.

The battery capacity is the value measured by the UPS microprocessor. It is expressed in Ampere-hours. This
value changes over time depending on the parameters of the battery itself and its environment. This measurement
is used to check that the battery is capable of supplying the rated power in the event of a mains outage.

The backup time is the value calculated by the UPS microprocessor on the basis of measurements carried out on
the battery. It is expressed in minutes. The calculation uses the percent load and the battery charge status at the
time of the measurement.

The load level is the ratio between the power supplied by the UPS to the load at the time of the measurement and
the rated output of the UPS. It is expressed as a percentage.

Maintenance

5.0 Scope

Maintenance procedures include preventive maintenance, isolation procedures for maintenance, startup for single
and parallel units after isolation, functional and visual checks, software options and configurations, and testing
scenarios.

5.1 Preventive Maintenance

The following preventive maintenance routines should be considered the minimum requirements; your installation
and site may require additional preventive maintenance to assure optimal performance from your installed Galaxy
PW™ and associated equipment. These routines should be performed twice a year (more often if required). We
strongly recommend contracting MGE Customer Support Services for preventive and remedial maintenance.

The technician or electrician performing preventive maintenance on the UPS must read thoroughly this manual
Galaxy PW™ Installation and Users Manual (MGE PN 86-133060-00) and be familiar with the indicators, controls,
and operation of the UPS prior to maintenance.

Technician or Engineer checks for preventive maintenance:

a. Isolate and de-energize all Galaxy PW™ equipment for all maintenance operations.

b. Ensure that all equipment is clean and free of loose dust, dirt, and debris. The exterior of the enclosures may

be cleaned with a mild solution of soap and water, lightly applied with a lint-free cloth.

c. Inspect the air intake and exhaust plates and clean as required. Verify that air flows freely through the

equipment. Clean the air intake and exhaust plates, and the enclosure interior, with a vacuum cleaner.

d. The Galaxy PW™ module is equipped with air filters that should be changed at regular intervals. Inspect the

filters regularly to determine how long the filters will last in your installation.

e. Initiate the start-up procedure, as described in the Installation and Users Manual section 2.7 System Start-up,

page 2—10.

f. Test the main operating sequences as applicable to your equipment configuration and installation.

5 — 186-133060-00 A00 Maintenance

5.2 Replacement Parts

There are no user replaceable parts inside the Galaxy PW™.

Three levels of replacement parts are available for the Galaxy PW™ UPS. The three levels are designated A, B,
and C. The level that you should keep on hand for your installation will vary depending on the type of maintenance
planned on site, and the configuration of your UPS system. Having the replacement parts on hand will prevent any
unacceptable delays (due to time involved obtaining spare parts) during critical periods, such as system start-up.

Any items used during start-up will be replaced by MGE at no charge. Contact MGE Customer Support Services for
specific recommendations.

A description of each level is provided below:

Level Description

A This level of replacement parts consists of consumable items, specifically fuses and air filters. It is

recommended to have these items on hand during installation of the UPS systems, including initial
start-up.

B This level of replacement parts is recommended when the user can tolerate short-duration UPS down-

time to obtain replacement parts in the event of a major UPS failure. This level of replacement parts
consists of consumable items, specifically fuses, air filters, an inverter leg, and the most critical circuit
board assemblies.

C This level of replacement parts is recommended when the user can tolerate only a minimum of down-

time in the event of a major UPS failure. This level of replacement parts consists of consumable items,
specifically fuses, air filters, an inverter leg, and a complete set of circuit board assemblies.

5.2 Maintenance Isolation Procedures

CAUTION PARALLEL UPS WITH EXTERNAL MAINTENANCE BYPASS During mainte-

nance operation, when CB1 (MBP) is closed and CB2 (UPS ISOLATION) is
open, each UPS control panel display will show a message “LOAD
PROTECTED” when the UPS is placed in ON-LINE MODE. In this mode the
critical load is not protected because it is supplied by the maintenance
bypass power.

5.2.1 Single UPS Unit

5.4 Battery Maintenance

Consult the instructions supplied by the battery manufacturer. Below are a few general indications:

◗ Sealed lead-acid Batteries:

- these batteries require no maintenance, but check the terminals of each cell from time to time and clean
if necessary.

◗ Vented lead-acid Batteries:

- check the electrolyte level regularly and add water if necessary,

- check the voltage of each cell to determine if it is necessary to equalize the battery,

- check the terminals of each cell and clean if necessary.

5.5 Visual Check

Power down the system prior to any maintenance operations.

NOTE In redundant parallel UPS systems the check may be carried out successively on

each UPS unit without interrupting the load. In other configurations, the load
must be supplied via the maintenance bypass (see "maintenance bypass" in the
"Alarm" section).

1. Clean the system regularly, particularly the air filter inlet and outlet grills. Check that the air circulates freely in
the cabinets. Use a vacuum cleaner if necessary.

2. Check that nothing hinders the ventilation at the top and at the back of the system.

5.6 Functional System Checks

1. Check that lights 1 , 2 and 3 on the control panel are not red, to avoid an interruption in the supply of power
to the load due to incorrect transfer conditions or a battery problem.

2. Press the "inverter OFF" button and check that the buzzer and control panel lights function correctly (see the
section on operating modes in the introduction).

3. Press the "inverter ON" button and check again that the control panel lights function correctly.

4. Run a transfer to battery test. With the inverter on, open input circuit breaker Q1. The orange "battery" light on
the control panel should light. After two minutes on battery power, close input circuit breaker Q1. The
rectifier/charger should automatically restart and the orange "battery" light on the control panel should go off.
