PRECAUTIONS REGARDING BATTERIES
Before operating the system, carefully read the battery and battery cabinet operating manuals.

Follow the directions below when using the batteries, otherwise liquid leakage, heat evolution,
and explosions may be caused.
a. Do not solder the batteries directly.
b. Do not charge the battery with its negative and positive terminals reversed.
c. Do not use different types or suppliers of batteries, or old and new batteries together.
d. Do not remove or damage the armoring tube of the battery.
e. Do not render a large impact or throw the battery.
f. Use wet cloths for cleaning the battery. Do not use organic solvents such as gasoline and
thinner, or oil. Do not wipe the battery with cloths that contain organic solvents or oil. Keep
the battery away from flexible vinyl materials.
g. Since the electric energy remains in the used batteries, treat them carefully to prevent
sparks and short circuits.
APPLICATION
CAUTION
If the UPS System is to be applied to support equipment that could affect human safety,
the following steps must be adhered to:
1. Consult with Mitsubishi Electric Power Products Inc. UPS Division.
2. Special consideration of the overall back up power system configuration is required so that
the Mitsubishi UPS System is not the sole support required for operation, maintenance and
management of power availability. Other available power sources; for example utility,
emergency power generation or other systems shall also support power availability.
Definition of equipment that could affect human safety:

Life Support Systems (is a system whose failure to perform can be expected to result in
bodily injury or death.)

Essential Public Systems (is a system whose failure to perform can be expected to
result in bodily injury or death and/or property damage.)
