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. Re-
pairs and battery replacement 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 batter-
ies 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 and 24VDC
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:
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 disco-
nnecting the battery terminals.
6. Determine if the battery is inadvertently grounded. If the bat-
tery 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:
Please read all of the WARNINGS and CAUTIONS before attempting to service
the batteries.
