REPLACING THE BATTERY
WARNING! This UPS contains potentially hazardous voltages. Do not at-
tempt 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.
CAUTION: Do not open or mutilate batteries. Released electrolyte is harmful
to the skin and eyes and may be toxic.
(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.
CAUTION: The battery system can present a risk of electrical shock. These
batteries produce sufficient current to burn wire or tools very rapidly, produc-
ing 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 redu-
ced, if such grounds are removed during installation and maintenance.
Please read all of the WARNINGS and CAUTIONS before attempting to ser-
vice 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.
Chapter 6: Replacing the Battery
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.
