8. Test and Commissioning Overview
8.1 System
All Alpha power system components undergo thorough factory testing. All levels/alarms are set to predetermined
values as detailed in their individual component manuals except where custom levels are specified. Good instal-
lation practice is to check the operation of all features and alarms and to set the power system levels in accor-
dance with the specific requirements of your system.
The individual system component manuals detail the methodology for testing and calibration of all components.
8.2 Battery
After installation of batteries it is usually necessary to “initial charge” the batteries to ensure proper operation
and to eliminate plate sulfation. Follow guidelines supplied with the battery and record initial charge readings; i.e.
specific gravity, cell voltage, charge current and temperature.
Battery warranty may be void if batteries are not initially charged following the manufacture's guidelines – with
proper records maintained.
Some VRLA batteries do not require initial charging, if placed on charge within 3-6 months of manufacture, check
with the manufacturer.
After the equalization period battery voltage should be reduced to the recommended float level.
Once the batteries have been initial charged it is suggested to perform a short duration high rate discharge test
on the batteries to verify the connections on the batteries and also to verify that there are no open or failed cells.
Cell voltages should be monitored during this process:
• Discharge for 15 minutes at the C/8 rate.
• Record cell voltages every 5 minutes.
• Check for overheating connections.
8.3 Documentation
Complete all necessary documentation; i.e., battery reports, DC wiring lists, AC distribution tables, floor plans,
etc. Tag wires, fill out identification strips, and identify circuit breakers.
