DANGER
Each battery string is an energy source in itself. Do not attempt to
access any internal area of the battery string yourself. Voltages are
always present in the battery strings. If you suspect that a battery
string needs service, contact your service representative.
Observe these precautions when working on or around batteries:
• Remove watches, rings, or other metal objects.
• Use insulated tools.
• Wear rubber gloves and boots.
• Do not lay tools or metal parts on top of batteries or battery
cabinets.
• Prior to connecting or disconnecting terminal, disconnect the
charging source.
• 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 is
reduced if such grounds are removed during installation and
maintenance.
• When replacing batteries, use the same number of sealed, lead-acid
batteries.
• Dispose of batteries according to your local codes for disposal
requirements.
• Do not dispose of batteries in a fire. Batteries may explode when
exposed to flame.
• Do not open or mutilate batteries. Released electrolyte is harmful to
the skin and eyes. It may be toxic.
9.2 Performing preventative maintenance
The UPS system requires very little preventative maintenance. However,
inspect the system periodically to verify that the units are operating
normally and that the batteries are in good condition.
