Safety Precaution - Mitsubishi Electric 9900D Series Owner Technical Manual

WARNING
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
•
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
•
Ask professional agents for wiring work. Inappropriate wiring work may cause electric shocks,
injuries, or fire.
PRECAUTIONS TO PROFESSIONAL AGENTS
•
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
•
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.
