Charging Batteries
Before you start to charge batteries read the “Important Safety Instructions” on
page v and take all safety precautions when working with batteries.
To charge your batteries:
1. If possible, disconnect all loads from the battery, by opening a disconnect
switch, or by switching loads off.
2. Ventilate the area around the battery thoroughly. Review the charging
instructions supplied by the manufacturer of your batteries and take any steps
required.
3. Apply AC power to the BC Series by closing the AC breaker and/or applying
shorepower or turning the generator on. The indicator lights will blink as an
initialization sequence runs, lasting typically 10 s or so. After initialization the
charging indicator light illuminates.
During charging, the charging current indicator lights show the total current
being delivered to the selected battery bank as well as any DC load applied.
4. Re-connect all loads to the battery, by closing a disconnect switch, or by
switching the loads on.
