• When the inverter capacity is larger than the motor capacity, select the MCCB and the MC according to the inverter model,
and select cables and the reactor according to the motor output.
• When the breaker installed on the inverter input side is shut off, check for the wiring fault (short circuit), damage to internal
parts of the inverter etc. The cause of the output shutoff must be identified and removed before turning ON the power of the
breaker.
• The matrix shows the MC selected according to the standards of Japan Electrical Manufacturers' Association (JEM standards)
for AC-1 class. The electrical durability of magnetic contactor is 500,000 times. When the MC is used for emergency stops
during motor driving, the electrical durability is 25 times. If using the MC for emergency stop during motor driving, select the
MC for the inverter input current according to the rated current against JEM 1038 standards for AC-3 class. When installing
an MC on the inverter output side to switch to the commercial-power supply operation while running a general-purpose motor,
select the MC for the rated motor current according to the rated current against JEM 1038 standards for AC-3 class.
• When the inverter capacity is larger than the motor capacity, select the MCCB and the MC according to the inverter model,
and select cables and the reactor according to the motor output.
