6 Maintenance
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.
Observe the following precautions 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 input power 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, 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.
6.1 Replacing Batteries
WARNING! Risk of electric shock. Can cause injury or death. Disconnect all local and remote electric power
supplies before working with the UPS. Ensure that the unit is shut down and power has been disconnected
before beginning any maintenance.
WARNING! Risk of electric shock and explosion. Can cause equipment damage, injury and death. Do not
dispose of the battery in a fire. The battery may explode. Do not open or damage the battery. Released
electrolyte is toxic and is harmful to skin and eyes. If electrolyte comes into contact with the skin, wash the
affected area immediately with plenty of clean water and get medical attention.
WARNING! Risk of electric shock. Can cause equipment damage, injury and death. A battery can present a

battery is replaced by an incorrect type. Dispose of used batteries according to the instructions included with
the battery-pack.
Read all safety cautions before proceeding. A trained user can replace the internal battery pack when the UPS is in a
