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 it is inadvertently grounded, remove
the source of the ground. Contact with any part of a grounded battery can result in electri-
cal shock. The likelihood of such shock will be reduced if grounds are removed during
installation and maintenance (applicable to a UPS and a remote battery supply not having
a grounded supply circuit).
