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. 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 the inside of this product
is charged. Doing so may cause 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 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.
