5.4 Battery Maintenance
Consult the instructions supplied by the battery manufacturer. Below are a few general indications:
◗
Sealed lead-acid Batteries:
- these batteries require no maintenance, but check the terminals of each cell from time to time and clean
if necessary.
◗
Vented lead-acid Batteries:
- check the electrolyte level regularly and add water if necessary,
- check the voltage of each cell to determine if it is necessary to equalize the battery,
- check the terminals of each cell and clean if necessary.
5.5 Visual Check
Power down the system prior to any maintenance operations.
NOTE In redundant parallel UPS systems the check may be carried out successively on
each UPS unit without interrupting the load. In other configurations, the load
must be supplied via the maintenance bypass (see "maintenance bypass" in the
"Alarm" section).
1. Clean the system regularly, particularly the air filter inlet and outlet grills. Check that the air circulates freely in
the cabinets. Use a vacuum cleaner if necessary.
2. Check that nothing hinders the ventilation at the top and at the back of the system.
5.6 Functional System Checks
1. Check that lights 1 , 2 and 3 on the control panel are not red, to avoid an interruption in the supply of power
to the load due to incorrect transfer conditions or a battery problem.
2. Press the "inverter OFF" button and check that the buzzer and control panel lights function correctly (see the
section on operating modes in the introduction).
3. Press the "inverter ON" button and check again that the control panel lights function correctly.
4. Run a transfer to battery test. With the inverter on, open input circuit breaker Q1. The orange "battery" light on
the control panel should light. After two minutes on battery power, close input circuit breaker Q1. The
rectifier/charger should automatically restart and the orange "battery" light on the control panel should go off.
