 Electric Shock Prevention
WARNING
 Do not remove the front cover or the wiring cover while the power of the inverter is ON, and do not run the inverter with the front cover or the
wiring cover removed. Otherwise you may access the exposed high voltage terminals or the charging part of the circuitry and get an electric
shock.
 Do not remove the inverter front cover even if the power supply is disconnected. The only exception for this would be when performing wiring
and periodic inspection. You may accidentally touch the charged inverter circuits and get an electric shock.
 Before wiring or inspection, LED indication of the inverter unit operation panel must be switched 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 is no residual voltage using
a tester or the like. For some time after the power-OFF, a high voltage remains in the smoothing capacitor, and it is dangerous.
 Any person who is involved in wiring or inspection of this product 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.
 Do not touch the plug-in option or handle the cables 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.
