 Electric Shock Prevention
Warning
 While the inverter power is ON, do not open the front cover or the wiring cover. 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 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.
 Do not touch the plug-in option 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.
 Injury Prevention
Caution
 The voltage applied to each terminal must be the ones specified in the Instruction Manual. Otherwise a burst, damage, etc. may occur.
 The cables must be connected to the correct terminals. Otherwise a burst, damage, etc. may occur.
 The polarity (+ and -) must be correct. Otherwise a burst or damage may occur.
 While power is ON or for some time after power OFF, do not touch the inverter as it will be extremely hot. Touching these devices may cause a burn.
