• Do not support the inverter by its terminal block 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.
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.
• Do not get on a shipping box.
• Do not stack shipping boxes higher than the indicated information printed on those boxes.
Doing so could cause injuries.

Wiring

• 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 power lines. Use the
devices within the recommended current range.
• Use wires in the specified size.
• When wiring the inverter to the power supply of 500 kVA or more, be sure to connect an
optional DC reactor (DCR).
Otherwise, fire could occur.
• Do not use one multicore cable in order to connect several inverters with motors.
• Do not connect a surge killer to the inverter's output (secondary) circuit.
Doing so could cause fire.
• Be sure to connect the grounding wires without fail.
Otherwise, electric shock or fire could occur.
• Qualified electricians should carry out wiring.
• Be sure to perform wiring after turning the power off.
• Ground the inverter in compliance with the national or local electric code.
Otherwise, electric shock could occur.
• Be sure to perform wiring after installing the inverter body.
Otherwise, 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.
Otherwise fire or an accident could occur.
• Do not connect the power source wires to output terminals (U, V, and W).
• Do not insert a braking resistor between terminals P (+) and N (-), P1 and N (-), P (+) and
P1, DB and N (-), or P1 and DB.
Doing so could cause fire or an accident.
