7 MAINTENANCE
This section describes replacing the internal battery pack, precautions, checking the UPS status and
checking UPS functions.
WARNING! Risk of electric shock. Can cause equipment damage, injury and death. 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.
• If the battery kit is damaged in any way or shows signs of leakage, contact your Vertiv™
representative immediately.
• Handle, transport and recycle batteries in accordance with local regulations.
• 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).
