Replacing Batteries
If a battery or string of batteries fails, becomes damaged, or wears out its life, you can replace
the battery or string as described below. Replacing batteries does not impact cabinet service,

recommends connecting an external generator to the cabinet while performing battery
maintenance to ensure service continuity in the event of an AC outage.
WARNING!

qualified technician should perform this procedure.
CAUTION!
Electrical, chemical, fire, and heat hazard. Handle batteries with
care to avoid personal injury or damage to the equipment.
