2�4 EMC Jumper/Screw
The AC drive has built-in safety capacitor� If the leakage current of the entire system is too large at power-on and the RCD acts, you can
cut the EMC jumper or remove the EMC screw to reduce leakage current to ground�
The position and cutting method of the EMC jumper is shown in the following gure.
