Galaxy PWTM 100 to 225 kVA
battery maintenance
Consult the instructions supplied by the battery manufacturer. Below are a few general indications:
■sealed
■vented
❏check the electrolyte level regularly and add water if necessary,
❏check the voltage of each cell to deter- mine if it is necessary to equalize the bat- tery,
❏check the terminals of each cell and clean if necessary.
CAUTION
Battery maintenance is undertaken with the system powered up. Operations must be carried out in accordance with applicable safety regula- tions by qualified personnel using insulated tools, gloves and safety goggles.
Batteries contain danger- ous substances that will harm the environment if thrown away. If you change the bat- teries yourself, call on quali- fied organizations for battery recovery and recycling.
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);
■clean the system regularly, particularly the air filter inlet and outlet grills. Check that the air circulates freely in the cabi- nets. Use a vacuum cleaner if necessary;
■check that nothing hinders the ventila- tion at the top and at the back of the sys- tem.
functional check
■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;
■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);
■press the "inverter ON" button and check again that the control panel lights function correctly;
■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 automati- cally restart and the orange "battery" light on the control panel should go off;
■in parallel systems, run these tests on each UPS unit.
