Chapter 8: Replacing the Battery
QUALIFIED SERVICE PERSONNEL ONLY
Please read all the
WARNINGS
and
CAUTIONS
before attempting to service
the batteries.
Typical battery life is 3 to 5 years. Environmental factors do
affect battery life. High temperatures, poor utility power, and frequent, short
duration discharges have a negative impact on battery life.
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 replacement
must be performed by
QUALIFIED SERVICE PERSONNEL ONLY.
CAUTION:
Do not open or mutilate batteries. Released electrolyte is harmful
to the skin and eyes and may be toxic.
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.
CAUTION:
The battery system can present a risk of electrical shock. These
batteries produce enough current to burn wire or tools very rapidly, producing
molten metal. Observe these precautions when replacing the batteries:
1.
Remove watches, rings, or other metal objects.
2.
Use hand tools with insulated handles.
3.
Wear protective eye gear (goggles), rubber gloves and boots.
4.
Do not lay tools or other metal parts on top of batteries.
5. Disconnect the charging source prior to connecting or disconnecting the
battery terminals.
6. 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.
CAUTION:
Replace the batteries with the same number and type as originally
installed in the UPS. These batteries have pressure operated vents. These
UPSs contain sealed non-spillable maintenance-free lead acid batteries.
