4Commissioning and Preventive Maintenance

4.1.Pre-Commissioning Inspection

Environment

1.Ensure the DC system environment is suitable for operation.

2.Ensure that there is sufficient clearance around the system for service.

3.Ensure that there is no sign of damage to the DC system.

4.Consult with customer to disable installed customer alarms before servicing the unit. This will allow the unit to be serviced without creating false alarms.

Electrical Installation

1.Ensure that the DC wiring is properly installed, sized, terminated and identified.

2.Ensure that the AC wiring is properly installed, sized, terminated and identified.

3.Ensure that the battery is properly connected to the System.

4.Ensure that the DC output over-current protection devices are adequate for the size of wiring installed.

5.Ensure that the DC Positive is bonded to central office ground (- 48 volt system).

6.Note the resistance of the ground bond.

7.Note any currents flowing in the ground.

8.Record ambient temperature.

9.Verify that the battery polarity is correct.

10.If a battery disconnect device(s) is/are present, note the following for each device:

a.DC Voltage Rating.

b.DC Current Rating

c.Interrupting Current Rating

Battery Visual and Safety Inspection

1.Check the mechanical integrity of the battery framing, racking, or cabinet.

2.Check that the battery framing, racking or cabinet is adequately secured to the floor.

3.Check compliance with seismic zone requirements.

4.Check the general appearance and cleanliness of the battery.

5.Record the manufacturer, model number, and capacity of the battery string(s) on Site Form.

6.Record the batch number, date code, and serial number of each cell or mono-block, and any other pertinent information that is available on the battery cells on the Site Form.
