3. Power Connection and Grounding:
(1). Single phase and three phase connection:
Green/yellow wire is the ground wire.
(2). How to connect a 1Φ / 220 V power from a 3 Φ / 380 V power source
(3). The usage of AC 220V Lamp Connector
Industrial sewing machine use only, must not be used for any other purpose.
1. When a three phase 220 V servo motor used on single phase 200 ~ 240 V power, only connect brown
and blue wires. Use insulating tape to wrap up the black wire, in order to prevent the current leakage.
2. Green / Yellow wire must do the grounding.
Caution:If the power source does not have the neutral point, then this 1Φ / 220 V servo motor is
not suitable for this connection. Please ask supplier to offer our 3Φ / 380 V servo motor.
