10.Check the torque of all battery inter- cell connector in accordance with the battery manufacturer’s specifications.

4.2 Commissioning

Initial Set-up

1.Remove all rectifiers.

2.Disconnect battery by removing a link in each string or opening the battery disconnects.

3.Check that battery voltage does not appear on the system bus.

4.Disconnect all loads.

AC Power Up

WARNING: The dc power plant is supplied from a nominal high voltage ac voltage source. Keep the ac input enclosure cover in place when the system is operational or energized

1.Verify that all of the circuit breaker positions are labeled to the corresponding rectifier correctly.

2.Insert all rectifiers.

3.Turn all rectifier circuit breakers on.

4.Each rectifier should have green ON LED illuminated.

NOTE: When ac power is initially applied, there is a 60-second period during which no alarms are reported.

DC Power Up:

1.Verify with a voltmeter that the dc voltage is within 0.1 Vdc of the System Voltage

2.Adjust battery float voltage to negative (-)49 Vdc.

3.Verify System Low Voltage Alarm.

4.Adjust battery float voltage to negative (-)57 Vdc.

5.Verify System High Voltage Alarm.

6.Restore the battery float voltage to negative (-) 54.00 Vdc or desired voltage.

Rectifier Test:

1.To verify that all rectifiers are reporting correctly to the controller, navigate through the menu and verify that the status for every rectifier in the system is correct.

2.Remove any rectifier and verify that you get a Minor Relay Output for rectifier 1 of n failure.

3.Remove a second rectifier and verify that you get a Major Relay Output for rectifier 2 of n failure.
