WARNING:
• External batteries cannot be replaced during “normal operation” of the UPS.
The UPS devices have no internal battery.
• Servicing of batteries should be performed or supervised by personnel knowledgeable about
batteries and the required precautions.
• The batteries installed in the UPS and in the external battery cabinets contain electrolyte. Under
normal conditions the containers are dry. A damaged battery may leak electrolyte that can be
dangerous in contact with the skin and cause irritation to the eyes. Should this happen, wash the
affected part with copious amounts of water and seek immediate medical attention.
• When replacing batteries, replace with the same type and number of batteries or battery packs.
• Do not dispose of batteries in a fire. The batteries may explode. Dispose of used batteries according to
the instructions
• Do not open or damage the battery cases. Released electrolyte is harmful to the skin and eyes and
may be toxic.
• 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 or other metal objects
• Use tools with insulated handles
• Wear rubber gloves and boots
• Do not short or bridge the battery terminals with any object.
• Unplug and turn off the UPS before performing battery replacement.
• Do not connect or disconnect the battery module(s) while the UPS is operating from the battery supply.
• 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 in inadvertently grounded. If inadvertently grounded, remove source from
the ground. Contact with any part of a grounded battery can result in electrical shock. The
likelihood of such shock can be reduced if such grounds are removed during installation and
maintenance (applicable to equipment and remote battery supplies not having a grounded supply
circuit).
