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 ††† are indicated in parentheses ( ).
