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 electrical 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).
