Electric shock prevention
WARNING
Do not remove the front cover or the wiring cover while the power of this product is ON, and do not run this product 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 this product
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.
This product 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 of this product 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.
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 wed 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. Doing so may cause an electric shock.
Never touch the motor terminals, etc. right after powering OFF as the DC voltage is applied to the motor for 1 second at
powering OFF if the main circuit capacitor capacity is measured. Doing so may cause an electric shock.
Before wiring or inspection for a PM motor, confirm that the PM motor is stopped as a PM motor is a synchronous motor
with high-performance 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 the output side of this product and keep it open
during wiring and inspection of this product. Otherwise you may get an electric shock.

so will cause the inverter shut off or damage the capacitor or surge suppressor. If any of the above devices is connected,
immediately remove it. When installing a molded case circuit breaker on the output side of the inverter, contact the
manufacturer of the molded case circuit breaker.
• Electromagnetic wave interference:
The input/output (main circuit) of the inverter includes high frequency components, which may interfere with the
communication devices (such as AM radios) used near the inverter. To minimize interference, enabling the built-in EMC filter
or installing an external EMC filters is effective. (Refer to page 88.)
• For details of options and peripheral devices, refer to the respective Instruction Manual.
• A PM motor cannot be driven by the commercial power supply.
• A PM motor is a motor with permanent magnets embedded inside. High voltage is generated at the motor terminals while the
motor is running. Before closing the contactor at the output side, make sure that the inverter power is ON and the motor is
stopped.
2.1.2Peripheral devices
Check the model of the inverter you purchased. Appropriate peripheral devices must be selected according to the capacity.
