Batteries can present a risk of electrical shock or burn from high short-circuit current. The
following precautions should be observed: 1) Remove watches, rings, or other metal
objects; 2) Use tools with insulated handles; 3) Do not lay tools or metal parts on top of
batteries.
S
ELECTRIC ENERGY HAZARD. Do not attempt to alter any battery wiring or connectors.
Attempting to alter wiring can cause injury.
S
Replace batteries with the same number and type of batteries as originally installed in
the UPS.
To replace the batteries:
1.
Use the same number and type of battery.
To ensure continued superior performance of your UPS and to
maintain proper charger operation, you must replace the batteries in
the UPS or its external battery cabinets or racks with the same
number of batteries. These batteries must be the same type as the
original batteries: valve-regulated, low-maintenance. The
replacement batteries should have the same voltage and
ampere-hour rating as the original batteries.
2.
Remove the ground from the battery terminal.
If your local or national code requires you to ground either battery
terminal, remove the connection from the terminal to ground (or
earth) before you work on the batteries. If any battery terminal is
inadvertently grounded, remove the source of the ground.
Contacting any part of a grounded battery can cause a risk of
electric shock. An electric shock will be less likely if you disconnect
the grounding connection before you work on the batteries.
