Maintenance
The components inside the battery cabinet are secured to a sturdy metal frame.
All batteries and repairable parts are located for easy removal with very little
disassembly. This design allows authorized service personnel to perform routine
maintenance and servicing quickly.
Schedule periodic performance checks of your battery system to keep it running
properly. Regular routine checks of battery parameters enable your system to
function efficiently for many trouble‐free years.

LETHAL VOLTAGE PRESENT. This unit should not be operated with the cabinet doors open or protective
panels removed. Do not make any assumptions about the electrical state of any cabinet in the UPS
system.
Because each battery string is an energy source in itself, opening the battery circuit
breaker does not de‐energize the voltage within the battery string.
DO NOT ATTEMPT
TO ACCESS ANY INTERNAL AREA OF THE BATTERY STRING YOURSELF. VOLTAGES ARE
ALWAYS PRESENT IN THE BATTERY STRING.
If you suspect that a battery string needs
service, you should contact your service representative.
If the string requires service, refer to the battery manufacturer's operating manual for
instructions on battery maintenance or contact your service representative.
Observe these precautions when working on or around batteries:
S
Remove watches, rings, or other metal objects.
S
Use tools with insulated handles.
S
Wear rubber gloves and boots.
S
Do not lay tools or metal parts on top of batteries or battery cabinets.
S
Disconnect the charging source prior to connecting or disconnecting terminals.
S
Determine if the battery is inadvertently grounded. If it is, remove the source of the
ground. Contact with any part of a grounded battery can result in electrical shock.
The likelihood of such shock is reduced if such grounds are removed during
installation and maintenance.
S
When replacing batteries, use the same number of sealed, lead‐acid batteries.
S
Proper disposal of batteries is required. Refer to your local codes for disposal
requirements.
S
Never dispose of batteries in a fire. Batteries may explode when exposed to flame.
S
Do not open or mutilate batteries. Released electrolyte is harmful to the skin and
eyes. It may be toxic.
