Safety instructions
Do not attempt to install, operate, maintain or inspect the
product until you have read through this Instruction Manual
and appended 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. Doing so may cause an electric shock.
 Even if power is OFF, do not remove the front cover except for wiring or
periodic inspection as you may accidentally touch the charged circuits of
this product and 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.
 The product body must be installed before wiring. Otherwise you may get
an electric shock or be injured.
 Setting dial and 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 change the cooling fan while power is ON. It is dangerous to
change the cooling fan while power is ON.
 Do not touch the printed circuit board or handle the cables with wet hands.
Otherwise you may get an electric shock.
 When measuring the main circuit capacitor capacity, the DC voltage is
applied to the motor for 1s at powering OFF. Never touch the motor
terminal, etc. right after powering OFF to prevent an electric shock.

is running even after the inverter power is turned OFF. Before wiring or
inspection, the motor must be confirmed to be stopped. In an application,
such as fan and blower, where the motor is driven by the load, a low-
voltage manual motor starter must be connected at the inverter's output
side, and wiring and inspection must be performed while the motor starter
is open. Otherwise you may get an electric shock.
