IMPORTANT SAFETY INSTRUCTIONS
a) The servicing of batteries requires battery knowledge and should only be carried out or
supervised by qualified electricians familiar with batteries. Keep unauthorized personnel
away from batteries.
b) Use identical battery types and numbers when replacing batteries. See battery supplier
manual for further details.
c) CAUTION - Do not dispose of batteries in a fire. Batteries may explode.
d) CAUTION - Avoid rough treatment and opening of batteries. Released electrolyte is harmful
to skin and eyes, and may be toxic.
e) CAUTION - Batteries may cause electric shocks and high voltage short-circuit current.
Follow the precautions below when working with batteries:
1. Remove watches, rings and other metal objects
2. Use tools with insulated handles
3. Wear rubber gloves and boots
4. Do not leave tools or metal parts on top of batteries
5. Disconnect charging source prior to connecting batteries
6. Determine if the battery is inadvertently grounded. If inadvertently grounded, remove
unwanted ground source. Any contact with grounded batteries may result in electric
shocks. The likelihood of such shocks will be reduced if grounds are removed during
installation and maintenance.
WARNING!
The entire system contains HAZARDOUS AC/DC VOLTAGES from several power sources.
Some terminals and components are live even with the system being switched off!
ONLY qualified electricians may install batteries and national and local codes must be followed.
NO APC Silcon UPS may have built-in batteries if connected to external batteries!
