3. Battery Cabinet Installation
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.
