Installation
• Install the inverter on a nonflammable material such as metal.
Otherwise fire could occur.
• Do not place flammable object nearby.
Doing so could cause fire.
• 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 supply, insert a recommended molded case circuit
breaker (MCCB) or residual-current-operated protective device (RCD)/a ground fault
circuit interrupter (GFCI)(with overcurrent protection). Use the devices within the
recommended current range.
• Use wires in the specified size.
• When wiring the inverter to the power supply that is 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.
• Ground the inverter in compliance with the national or local electric code.
Otherwise, electric shock could occur.
• Qualified electricians should carry out wiring.
• Be sure to perform wiring after turning the power OFF.
Otherwise, electric shock could occur.
• Be sure to perform wiring after installing the inverter body.
Otherwise, electric shock or injuries could occur.
