Safety instructions
Do not attempt to install, operate, maintain or inspect the
product until you have read through this Instruction Manual
and supplementary documents carefully and can use the
equipment correctly. Do not use this product until you have a
full knowledge of the equipment, safety information and
instructions.
Installation, operation, maintenance and inspection must be
performed by qualified personnel. Here, qualified personnel
means personnel who meets all the following conditions.
• A person who took a proper engineering training. 
Such training may be available at your local Mitsubishi
Electric office. Contact your local sales office for schedules
and locations.
• A person who can access operating manuals for the
protective devices (e.g. light curtain) connected to the safety
control system. A person who has read and familiarized
themselves with the manuals.
In this Instruction Manual, the safety instruction levels are
classified into "WARNING" and "CAUTION"
Incorrect handling may cause hazardous

follow the instructions of both levels as they are critical to
personnel safety.
 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 display of the operation panel
is OFF. Any person who is involved in wiring or inspection shall wait for
10 minutes or longer after power 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.
 This 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 for 400 V class inverter to be compliant with EN standard.
 Any person who is involved in wiring or inspection of this equipment shall
be fully competent to do the work.
 This product body must be installed before wiring. Otherwise you may get
an electric shock or be injured.
 Do not touch the setting dial or keys with wet hands. Doing so may cause
an electric shock.
 Do not subject the cables to scratches, excessive stress, heavy loads or
pinching. Doing so may cause an electric shock.
 Do not change the cooling fan while power is ON as it is dangerous.
 Do not touch the printed circuit board or handle the cables with wet hands.
Otherwise you may get an electric shock.

 Additional instructions
The following instructions must be also followed. If the product
is handled incorrectly, it may cause unexpected fault, an injury,
or an electric shock.
Transportation and installation
 To prevent injury, wear cut-resistant gloves when opening packaging with

magnets embedded inside and high-voltage is generated at the motor
terminals while the motor is running even after the power of this product is
turned OFF. In an application, such as fan and blower, that the motor may
be driven by the load, connect a low-voltage manual contactor at this
