1.0 INTRODUCTION
The Mitsubishi Uninterruptible Power Supply System (UPS) is designed to provide many years of
reliable protection from power failure, brown-outs, line noise, and voltage transients. To ensure
optimum performance of the equipment, follow the manufacturer's instructions. This manual
contains descriptions required to operate the UPS. Please read this manual carefully and retain it
for future reference.
This manual contains important instructions for the 9900D SERIES Uninterruptible Power Supply
System that should be followed during installation and maintenance of the UPS and batteries.
Lethal voltages exist within the equipment during operation. Observe all warning
and cautions in this manual. Failure to comply may result in serious injury or death.
Obtain qualified service for this equipment as instructed.

1.1 SAFETY PRECAUTIONS
In order to maintain safety and perform start-up and maintenance of the UPS system
successfully, certified service personnel familiar with the operation of this equipment must be
involved. The following safety practices should always be followed.
PRECAUTIONS DURING INSTALLATION
CAUTION
•Do not block the ventilation ports. The ventilation ports should be arranged so that walls or
ceilings do not block ventilation. (Maintenance spaces described in the catalogue or external
drawings should be followed.)
If a ventilation port is blocked, the internal temperature of the UPS will rise, and consequently, a
fire may be caused due to liquid leakage from batteries, short-circuits, or parts deterioration.
PRECAUTIONS FOR WIRING
CAUTION
•
Ask professional agents for wiring work. Inappropriate wiring work may cause electric shocks,
injuries, or fire.
PRECAUTIONS TO PROFESSIONAL AGENTS
CAUTION
•
Use wiring conduit, pits or racks for input/output wiring. Inadvertent wiring may cause injuries.
•
Use terminals for connection to the input/output terminals. Inadvertent connection may cause
electric shocks.
•
Do not drop dust or any other thing from the fan hole.
PRECAUTIONS FOR UPS OR UPS PARTS DISPOSAL
CAUTION
•
Since the UPS contain special industrial waste, such as capacitors, insulators or batteries, they
cannot be disposed of like other general waste. Please check the disposal guideline of your
district, contact the specialized contractor for disposal.

PRECAUTIONS REGARDING BATTERIES
Before operating the system, carefully read the battery and battery cabinet operating manuals.
CAUTION
•
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 i
n 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.)
