REPLACING THE BATTERY
(Authorized Service Personnel)
CAUTION!
Read and follow the IMPORTANT SAFETY INSTRUCTIONS before servicing the bat-
tery. Service the battery under the supervision of Authorized Service Personnel knowledgeable of
batteries and their precautions.
CAUTION!
Use only the specified type of battery. See your dealer for replacement batteries.
CAUTION!
The battery may present risk of electrical shock. Do not dispose of battery in a fire, as it
may explode. Follow all local ordinances regarding proper disposal of batteries.
CAUTION!
Do not open or mutilate the batteries. Released electrolyte is harmful to skin and eyes
and may be toxic.
CAUTION!
Although the battery system voltage is only 12VDC, the battery can present a high risk of
short circuit current and electrical shock. The short circuit current capability of the battery is sufficient
to burn wire or tools very rapidly producing molten metal. Observe these precautions when replacing
the battery:
1. Remove all watches, rings or other metal objects.
2. Only use tools with insulated handles.
3. Do not lay tools or metal parts on top of battery or any terminals.
4. Wear protective eye gear (goggles), rubber gloves and boots.
5. Disconnect the charging source before connecting or disconnecting the battery terminals.
6. Determine if the battery is inadvertently grounded. If inadvertently grounded, remove the source
of ground. Contact with a grounded battery can result in electrical shock! The likelihood of such
shock will be reduced if; such grounds are removed during installation and maintenance (applica-
ble to a UPS and a remote battery supply not having a grounded circuit).
BATTERY REPLACEMENT PROCEDURE

2. Turn the UPS off and unplug the UPS’s power cord from the AC wall outlet.
