UPS System Installation
• Servicing should be performed by qualified service personnel knowledgeable of batteries and required
precautions. Keep unauthorized personnel away from batteries.
• Batteries can present a risk of electrical shock or burn from high short circuit current. The following
precautions should be observed: 1) Remove watches, rings, or other metal objects; 2) Use tools with
insulated handles; 3) Do not lay tools or metal parts on top of batteries; 4) Disconnect charging source prior
to connecting or disconnecting battery terminals; 5) Wear voltage rated gloves and electrical hazard
footwear.
• When replacing batteries, replace with the same type and number of batteries or battery packs. Contact
your service representative to order new batteries.
• Proper disposal of batteries is required. Refer to your local codes for disposal requirements.
• Never dispose of batteries in a fire. Batteries may explode when exposed to flame.
• Do not open or mutilate the battery or batteries. Released electrolyte is harmful to the skin and eyes and
may be extremely toxic.
• Determine if the battery is inadvertently grounded. If inadvertently grounded, remove source of ground.
Contact with any part of a grounded battery can result in electrical shock. The likelihood of such shock will
be reduced if such grounds are removed during installation and maintenance.
• ELECTRIC ENERGY HAZARD. Do not attempt to alter any battery wiring or connectors. Attempting to alter
wiring can cause injury.
