5.2 Test and commissioning overview
5.2.1 System
All power system components undergo thorough factory testing. All levels and alarms are set to values according to
the information given in the component manuals, unless custom levels are specified. Check the operation of all
features and alarms and ensure that the power system levels are set in accordance with the specific requirements
of your system. See the component manuals for more details.
5.2.2 Environmental/intrusion
Check the operation of all enclosure features, such as the air conditioning unit settings, the high/low temperature
alarms and the intrusion alarm.
5.3 Battery
After the batteries have been installed, the batteries must be “initially charged” to eliminate plate sulfation. Follow
the guidelines in the battery manual. Record the initial charge readings, which are: specific gravity, cell voltage,
charge current, and temperature. Battery warranty may be void if the batteries are not initially charged following the
manufacturer's guidelines and proper records maintained.
Some VRLA batteries do not require initial charging if they are placed on charge within 3-6 months of manufacture.
Check the battery manufacturer’s manual.
After the equalization period, reduce the battery voltage to the recommended float level.
Once the batteries have been initially charged, perform a short duration high rate discharge test on the batteries to
verify that the cable connections are good and that there are no open or failed cells. Monitor the cell voltages during
this process:

Discharge for 15 minutes at the C/8 rate.

Record cell voltages every 5 minutes.

Check for overheating connections.
5.3.1 Documentation


Battery reports.

DC wiring lists.

AC distribution tables.

Floor plans.

Fill out tag wire identification strips.

