• Do not support the inverter by its front cover during transportation.
Doing so could cause a drop of the inverter and injuries.
• Prevent lint, paper fibers, sawdust, dust, metallic chips, or other foreign materials from getting into the
inverter or from accumulating on the heat sink.
• When changing the positions of the top and bottom mounting bases, use only the specified screws.
Otherwise, a fire or an accident might result.
• Do not install or operate an inverter that is damaged or lacking parts.
Doing so could cause fire, an accident or injuries.
Wiring
• If no zero-phase current (earth leakage current) detective device such as a ground-fault relay is
installed in the upstream power supply line in order to avoid the entire power supply system's shutdown
undesirable to factory operation, install a residual-current-operated protective device (RCD)/earth
leakage circuit breaker (ELCB) individually to inverters to break the individual inverter power supply
lines only.
Otherwise, a fire could occur.
• When wiring the inverter to the power source, insert a recommended molded case circuit breaker
(MCCB) or residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB)
(with overcurrent protection) in the path of each pair of power lines to inverters. Use the recommended
devices within the recommended current capacity.
• Use wires in the specified size.
• Tighten terminals with specified torque.
Otherwise, a fire could occur.
• When there is more than one combination of an inverter and motor, do not use a multicore cable for the
purpose of handling their wirings together.
• Do not connect a surge killer to the inverter's output (secondary) circuit.
Doing so could cause a fire.
• Ground the inverter in compliance with the national or local electric code.
• Be sure to ground the inverter's grounding terminals
Otherwise, an electric shock or a fire could occur.
• Qualified electricians should carry out wiring.
• Be sure to perform wiring after turning the power OFF.
Otherwise, an electric shock could occur.
• Be sure to perform wiring after installing the inverter unit.
Otherwise, an electric shock or injuries could occur.
• Ensure that the number of input phases and the rated voltage of the product match the number of
phases and the voltage of the AC power supply to which the product is to be connected.
• When using this product in combination with a PWM converter, refer to the instructions given in the
User's Manual.
Otherwise, a fire or an accident could occur.
• Do not connect the power supply wires to the inverter output terminals (U, V, and W).
Doing so could cause fire or an accident.
