3. Battery Cabinet Installation
• External circuit protection devices (fuses or circuit breakers) must consider the
discharge rate of the battery, the wiring to be protected and the DC short circuit
current of the battery.
After performing the installation procedures in Section 7.:
1. Open the front door of the battery cabinet to access internal components. Use a
digital voltmeter when voltage measurements are required.
2. Determine if the battery has been inadvertently grounded by resetting the circuit
breaker to the ON position and measuring the voltage between the battery cabinet
grounding lug and the positive load connection point within the cabinet. This voltage
should measure
0 (zero) VDC. If the measured voltage is not zero, determine the cause and correct
before proceeding.
3. Return the internal circuit breaker to an open OFF position as a safety precaution
while connecting the output cables. Doing so prevents damage in the event the
cables are accidentally shorted.
4. The top of the battery cabinet includes knockouts for load connection cable entry.
Punch out the appropriate knockout and connect the conduit or cable bushing.
5. The output circuit breaker accommodates cables up to 600 MCM (300 mm
6. Connect an appropriate equipment grounding cable to the grounding lug located on
the top of the battery cabinet.
7. Feed the positive and negative cables (and "N" center, if equipped) from the open
external disconnect switch or the UPS battery field wiring terminals through the
conduit/cable bushing. Connect to the respective output terminals inside the battery
cabinet.

3.8 Final Electrical Check

Before closing any connecting circuit breaker or disconnect switch, complete these
verification steps:
1. Verify the battery cabinet output voltage is correct.
2. If battery cabinets will be operated in parallel, verify that the individual system output
voltages match within 2V DC.
3. Verify the voltage measured between either output terminal and the battery cabinet
ground is zero.
4. If any of the above verification steps show an irregularity, determine and correct the
cause before proceeding.
5. Reset the circuit breaker to the ON position.
