Warning
Do not remove the front cover or the wiring cover of the inverter while the inverter power is ON. Do not operate the inverter with any cover or wiring cover removed,
as accidental contact with exposed high-voltage terminals and internal components may occur, resulting in an electrical 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.
Do not touch the operation panel or handle the cables with wet hands. 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.
