Fire Prevention - Mitsubishi Electric FR-CS84-012 Instruction Manual

Electric shock prevention
WARNING
 Do not remove the front cover or the wiring cover while the inverter power is ON, and do not run the inverter with the
front cover or the wiring cover removed as the exposed high voltage terminals or the charging part of the circuitry can
be touched. Otherwise you may get an electric shock.
 Even if power is OFF, do not remove the front cover except for wiring or periodic inspection as the inside of the inverter
is charged. Otherwise you may get an electric shock.
 Before wiring or inspection, check that the LED display of the operation panel is OFF. Any person who is involved in
wiring or inspection shall wait for 10 minutes or longer after the power supply has been cut off, and check that there are
no residual voltage using a tester or the like. The capacitor is charged with high voltage for some time after power OFF,
and it is dangerous.
 The inverter must be earthed (grounded). Earthing (grounding) must conform to the requirements of national and local
safety regulations and electrical code (NEC section 250, IEC 61140 class 1 and other applicable standards). A neutral-
point earthed (grounded) power supply must be used to be compliant with EN standard.
 Any person who is involved in wiring or inspection of this product shall be fully competent to do the work.
 The product body must be installed before wiring. Otherwise you may get an electric shock or be injured.
 Key operations must be performed with dry hands to prevent an electric shock. Otherwise you may get an electric shock.
 Do not subject the cables to scratches, excessive stress, heavy loads or pinching. Otherwise you may get an electric
shock.
 Do not touch the printed circuit board or handle the cables with wet hands. Otherwise you may get an electric shock.
Fire prevention
CAUTION
 The inverter must be installed on a nonflammable wall without any through holes so that nobody touches the heatsink,
etc. on the rear side of the inverter. Installing it on or near flammable material may cause a fire.
 If the inverter has become faulty, the inverter power must be switched OFF. A continuous flow of large current may cause
a fire.
 Do not connect a resistor directly to the DC terminals P/+ and N/-. Doing so could cause a fire.
 Be sure to perform daily and periodic inspections as specified in the Instruction Manual. If this product is used without
any inspection, a burst, breakage, or a fire may occur.
Injury prevention
CAUTION
 The voltage applied to each terminal must be as specified in the Instruction Manual. Otherwise burst, damage, etc. may
occur.
 The cables must be connected to the correct terminals. Otherwise burst, damage, etc. may occur.
 The polarity (+ and -) must be correct. Otherwise burst, damage, etc. may occur.
 While power is ON or for some time after power-OFF, do not touch the inverter as it will be extremely hot. Touching these
devices may cause a burn.
