REPLACING THE BATTERY
WARNING!
This UPS contains potentially hazardous voltages. Do not attempt to
disassemble the UPS beyond the battery replacement procedure. This
UPS contains no user serviceable parts. Repairs and battery replace-
ment must be performed by QUALIFIED SERVICE PERSONNEL ONLY.
Do not open or mutilate batteries. Released electrolyte is harmful to
the skin and eyes and may be toxic.
CAUTION:
(QUALIFIED SERVICE PERSONNEL ONLY)
CAUTION:
Do not dispose of batteries in a fire. The batteries may explode. The
batteries in this UPS are recyclable. Dispose of the batteries properly.
The batteries contain lead and pose a hazard to the environment and
human health if not disposed of properly. Refer to local codes for
proper disposal requirements or return the battery to the supplier.
Although the battery system voltage is only 12VDC the battery system
can still present a risk of electrical shock. These batteries produce
sufficient current to burn wire or tools very rapidly, producing molten
metal. Observe these precautions when replacing the batteries:
CAUTION:
Please read all of the WARNINGS and CAUTIONS before attempting to service the
batteries.
Remove watches, rings, or other metal objects.
Use hand tools with insulated handles.
Wear protective eye gear (goggles), rubber gloves and boots.
Do not lay tools or other metal parts on top of batteries.
Disconnect the charging source prior to connecting or disconnect-
ing the battery terminals.
Determine if the battery is inadvertently grounded. If the battery is,
remove the source of the grounding. Contact with any part of a
grounded battery can result in an electrical shock. The likelihood of
such shock will be reduced, if such grounds are removed during
installation and maintenance.
