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:
• Remove watches, rings and other metal objects.
• Use tools with insulated handles.
• Wear rubber gloves and boots.
• Do not lay tools or metal parts on top of batteries.
• Disconnect charging source prior to connecting or disconnecting battery terminals.
• Determine if the battery is inadvertently grounded. If inadvertently grounded, remove
source of ground. Contact with any part of a grounded battery can result in electrical shock.
The likelihood of such shock will be reduced if such grounds are removed during installa-
tion and maintenance (applicable to a UPS and a remote battery supply not having a
grounded supply circuit).
