WARNING
While power is ON or when the inverter is running, do not
open the front cover. You may get an electric shock.
Do not run the inverter with the front cover or wiring cover
removed. Otherwise, you may access the exposed high-
voltage terminals and charging part and get an electric shock.
Even if power is OFF, do not remove the front cover except for
wiring or periodic inspection. You may accidentally touch the
charged inverter circuits and get an electric shock.
Before wiring or inspection, power must be switched OFF. To
confirm that, LED indication of the operation panel must be
checked. (It must be OFF.) Any person who is involved in
wiring or inspection shall wait for at least 10 minutes after the
power supply has been switched 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.
Any person who is involved in wiring or inspection of this
equipment shall be fully competent to do the work.
The plug-in option must be installed before wiring. Otherwise,
you may get an electric shock or be injured.
