11. Test and Commissioning Overview
11.1 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 installation
practice is to check the operation of all features and alarms and to set the power system levels in accordance with
the specific requirements of your system.
The individual system component manuals detail the methodology for testing and calibration of all components.
11.2 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.
11.3 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.
