IMPORTANT SAFETY INSTRUCTIONS FOR SERVICING BATTERIES
A. Servicing of batteries should be performed or
supervised by personnel knowledgeable with batteries
and the required precautions. Keep unauthorized
personnel away from batteries.
B. When replacing batteries, use the same model and
manufacturer of batteries.
C. CAUTION — Do not dispose of battery or batteries in a
fire. The battery may explode.
D. CAUTION — Do not open or mutilate the battery or
batteries. Released electrolyte is harmful to the skin
and eyes. It may be toxic.
E. CAUTION — A battery can present a risk of electrical
shock and high short-circuit current. The following
precautions should be observed when working with
batteries:
1. Remove watches, rings, or other metal objects.
2. Use tools with insulated handles.
3. Wear rubber gloves and boots.
4. Do not lay tools or metal parts on top of batteries.
5. Disconnect charging source prior to connecting or
disconnecting battery terminals.
6. Determine if ground faults exists. If so, remove the
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.
The following preventive maintenance routines should be
considered the minimum requirements; your installation and
site may require additional preventive maintenance to assure
optimal performance from your installed Comet UPS and
associated equipment. These routines should be performed
twice a year (more often if required). We strongly
recommend contracting MGE Customer Support Services for
preventive and remedial maintenance at 1-800-438-7373.
