2.Check the mechanical integrity of the battery framing, racking, or cabinet. Tighten where necessary.

3.If there is a battery disconnect device fitted, ensure that it is properly connected and protected.

4.Check the general appearance and cleanliness of the battery. Clean if necessary. Use only approved cleaning materials.

5.Visually inspect each cell for the following, and clean and neutralize if necessary. Document discrepancies on Site form accordingly.

a.Cracks.

b.Case leaks.

c.Post-seal leaks.

d.Pressure relief valve leaks (VRLA only).

e.Case swelling (VRLA only).

f.Terminal corrosion and connector corrosion.

6.Check the torque of all battery inter-cell connector in accordance with specifications. Re-torque if necessary (annual only).

7.Measure and record ambient temperature.

6.3Test

System Voltage Test

1.Verify with a voltmeter directly attached to the dc bus that the system voltage is correct.

2.System voltage should also agree with the battery float voltage set up in the battery parameters section. The system may be off because of battery temperature compensation or battery recharging.

Rectifier Current Test

1.Insert voltmeter probe between I+ and common jack on front of each rectifier.

2.Record current for each rectifier using the formula – Voltage X 10 amperes/volt.

3.Rectifier current displayed under Rectifier/Info should agree with the recorded current.

Rectifier Current Share Test

Verify that the highest rectifier current and the lowest rectifier current are within 5 A.

System Current Test

Verify the System current equal to the total of the rectifier currents. System current should equal the total current of the loads as well as any battery current.

Rectifier Alarm Test

1.Verify that all of the rectifiers report RFA Alarm is off.

2.Verify that the battery voltage reading on the voltmeter is negative (-)54.00 Vdc + 0.02 Vdc.

3.Remove 1 rectifier and verify that you get a Minor alarm for Rect 1 of n failure on the controller and the customer remote alarm panel.

4.Remove the second rectifier and verify that you get a Major alarm for Rect 2 of n failure on the controller and the customer remote alarm panel.
