SYSTEM DESCRIPTION AND OPERATION

Congratulations on your choice of the UPStation GXT™ Uninterruptible Power

System (UPS) Battery Cabinet. The battery cabinets greatly extend the backup

time of your UPS during a power outage. Either one or two optional cabinets

may be connected to the UPS.

When the UPS manual instructs the operator to close the battery circuit breaker

on the rear of the UPS, the operator should also close all of the circuit breakers

on the rear of the battery cabinets. Likewise, when the operator is instructed to

open the UPS battery circuit breaker, the circuit breakers on the optional battery

cabinets should also be opened.

CAUTION: When the UPS manual instructs the operator to open all circuit

breakers to fully isolate the UPS, be sure to open the circuit breakers on the

battery cabinets also.

MAINTENANCE

The UPStation GXT battery cabinets require very little maintenance. The

batteries are valve regulated, nonspillable, lead acid and should be kept charged

to obtain their designed life. The UPS continuously charges the batteries when

connected to the AC power supply.

When storing the UPS for any length of time, it is recommended to apply power

to the UPS for at least 24 hours every four to six months to ensure full recharge

of the batteries. In no case should the unit be stored in excess of nine months

without recharge. Periodically, examine the vents on the front and rear of the

cabinet, and remove any obstructions from the surface of the vents.

INSTALLATION INSTRUCTIONS

INSTALLATION CONSIDERATIONS

Detailed instructions to help you install the batteries are provided in the following

pages; however, you should give some consideration to the proposed

environment in which the UPS is to be installed, and carry out some preparatory

work.

WARNING: 240V BATTERIES – RISK OF ELECTRICAL SHOCK

Before installing, ensure that the UPS is shutdown, all circuit breakers on the rear

of the UPS and battery cabinets are off and the mains supply is locked off. For

safety, check with a DC voltmeter that no voltages exist on the battery positive-

negative terminals of both the UPS and the battery cabinets. Also check voltages

between these terminals and ground (earth) before touching or wiring to these

terminals.

UNPACKING AND INSPECTION

Follow unloading instructions printed on the carton. Do not discard any

packaging until installation is complete, check that you have removed to a safe

place the user manual, stabilizing brackets, and any other items shipped with the

unit to be used in its installation.

CAUTION: The GXT240VBATT models weigh up to 160 kg (353 lbs) and the

GXT240VLRT models weigh up to 395 kg (871 lbs). Use adequate handling aids

when moving or installing the UPS. The cabinet is fitted with castor wheels for

easy movement. Take care when the cabinet is removed from its packing and

being wheeled across an uneven floor without the stabilizers fitted so that it does

not tip over.

Before you install the battery cabinets, give it a thorough visual examination to

ensure it has not been subjected to shipping damage. If it is not in perfect

condition, you should advise both the shipper and the supplier immediately. DO

NOT ATTEMPT TO INSTALL A DAMAGED BATTERY CABINET.

LOCATION

Locate the batteries indoors in a controlled environment next to the UPS. Locate

it in an area with unrestricted airflow, away from water, flames, flammable liquids,

gases, corrosives, or conductive contaminants.

Give consideration to the airflow requirements and allow at least 150 mm (6

inches) free space around the cabinet, with a minimum of 300 mm (12 inches) at

the back to enable easy operator access to the rear panel mounted circuit

breakers.

Electrical maintenance/servicing requires access to all four sides of the battery

cabinets. Provide the necessary free space or use a flexible wiring system to

allow the cabinet to be pulled forward.

Maintain an ambient temperature range of 0 - 40° C (32-104° F)

Note: Operation in temperatures above 25°C (77°F) reduces battery life.

ELECTRICAL CONNECTIONS

The UPS and battery cabinets are supplied with battery terminals on the rear of

the UPS within a cable box. (see outline drawing) The cable box (gland plate)

can be removed to enable knockouts to be removed, or new holes drilled, to

secure the cables.

The cable sizes and distribution methods used during installation are subject to

local/national electrical codes of practice, and therefore are not detailed here.

Refer to the tables and wiring diagram in the UPS manual for your specific

model. Information is also provided on the battery cabinet rating plate. Rigid or

flexible conduit is recommended for all battery wiring.

The battery cabinet terminals will accept wire sizes up to the values below:

GXT6000 = 10 mm2(8 AWG) Recommended for all GXT6000 wiring.

GXT10000 = 16 mm2(6 AWG) Recommended for all GXT10000 wiring.

(75º C copper wire)

Terminal tightening torque is 40 cm-kg (35 in-lb).

In no case should the voltage drop on the battery cables exceed 2.0 volts at the

battery cabinet’s rated load.

Properly grounded (earthed) equipment provide multiple benefits.

High quality ground (earth) connections are required for the equipment ground

conductors (protective earth) and grounding electrode conductor (power system

earth connection) to reduce electrical noise and provide for safe operation of the

UPS and connected loads. Conduit used alone without a grounding conductor

wire is not an acceptable connection. Size ground (protective earth) conductors

equal to circuit conductors.

STABILIZERS / LEVELING FEET

When the battery cabinet is located in its final position before or after wiring, it is

necessary to fit stabilizer brackets and, if necessary, adjust the leveling feet. If

the UPS is wired using a rigid wiring system, then movement of the UPS must be

prevented by winding down the 4 leveling feet under the UPS as shown below.

For UPS wired with flexible cables, this is optional.

Adjust the leveling feet as necessary using a 12mm open-ended wrench. DO

NOT LOOSEN THE LARGER NUT ABOVE, AS THIS FIXES THE LEVELING

FEET TO THE CHASSIS.

Attach the stabilizing brackets as follows.

GXT240VBATT or GXT240VBATTUL models:

1. Using a Phillips-head screwdriver, remove the screws (4) from each of the

bottom corners of the side panels.

2. Attach the stabilizing brackets to each corner using screws just removed.

GXT240VLRT or GXT240VLRTUL models:

1. Using a Phillips-head screwdriver, remove the two inner-most screws at the

base of both side panels.

2. Attach the stabilizers fixing with the screws just removed.

COMMISSIONING THE UPS WITH OPTIONAL BATTERIES

1. BEFORE STARTING THE UPS OR CLOSING ANY CIRCUIT BREAKERS,

verify the proper wiring of the optional battery cabinets. Using a continuity

meter, verify that positive (+) terminals are only connected to positive

terminals on the rear of the UPS and battery cabinets. Again, check that

negative (-) terminals are only connected to negative terminals. Be sure to

check every wire interconnecting the UPS and optional battery cabinets.

Verify that the positive and negative terminals are not in contact with ground

(earth).

WARNING: REVERSING THE BATTERY CONNECTIONS CREATES A

SERIOUS HAZARD TO BOTH THE EQUIPMENT AND SERVICE

TECHNICIAN. CHECK THESE CONNECTIONS CAREFULLY BEFORE

TURNING ON ANY CIRCUIT BREAKERS.

2. Install the covers on the cable entry boxes.

3. Leave the circuit breakers on the rear of the battery cabinets off. Perform all

UPS commissioning instructions in the UPS manual using only the internal

batteries controlled by the circuit breaker on the rear of the UPS.

4. Next, commission the UPS again while leaving open the battery circuit

breaker on the rear of the UPS and closing all circuit breakers on the rear of

the optional battery cabinets.

5. Finally, check the UPS with all battery circuit breakers closed. The system is

now ready for normal operation.
