• Install the inverter on a base made of metal or other non-flammable material.
Otherwise, a fire could occur.
• Do not place flammable object nearby.
Doing so could cause fire.
• 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.
• If there isn’t zero-phase current (Earth leakage current) detective device, such as a ground-fault relay
in the upstream power supply line, which is to avoid undesirable system shutdown. Install a
residual-current-operated protective device (RCD)/earth leakage circuit breaker (ELCB) individually to
break the individual inverter’s power supply line.
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 running their wirings together.
• Do not connect a surge killer to the inverter's output (secondary) circuit.
Doing so could cause a fire.
• Be sure to ground the inverter's grounding terminals
G.
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.
