7-3 Connection Example
*2. The braking resistor has a temperature relay. If the relay begins
to operate, turn off the Inverter.
*3. For 400-V power supply, install a step-down transformer.
*4. Install a fuse in the operating circuit.
Not doing so may result in fire.
*5. If the main circuit is turned on at the same time as a RUN
command is input, the motor begins to rotate at least 2.0
seconds later.
Secure a duty cycle of 5 minutes or more between switching the
power ON/OFF. Otherwise, the life of the Inverter is shortened.
*6. Do not turn off the main circuit power supply during operation.
*7. Terminal symbols for 3G3MX-AE
