5.1 Precautions
Servicing of batteries should be performed or supervised by personnel knowledgeable
about batteries and the required precautions. (Please contact Powervar for Battery
Replacement)
When replacing batteries, replace with the same type and number of batteries or battery
packs.
CAUTION: Risk of explosion if battery is replaced by incorrect type.
Dispose of used batteries according to the instructions.
CAUTION
: Do not dispose of batteries in a fire. The batteries may explode.
CAUTION: Do not open or mutilate batteries. Released electrolytes are harmful to the
skin and eyes. It may be toxic.
CAUTION: A battery can present a risk of electrical shock and high short-circuit current.
The following precautions should be observed when working on batteries:
a) Remove watches, rings, or other metal objects.
b) Use tools with insulted handles.
c) Wear rubber gloves and boots.
d) Do not lay tools or metal parts on top of the batteries.
e) Disconnect charging source prior to connecting or disconnecting battery
terminals.
f) Determine if the battery is inadvertently grounded. If inadvertently grounded,
remove source from ground. Contact with any part of a grounded battery can
result in electrical shock. The likelihood of such shock can be reduced if such
grounds are removed during installation and maintenance (applicable to
equipment and remote battery supplies not have a grounded supply circuit).
