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
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 for safety.
2. Green / Yellow wire must be grounded well.
Caution：If the system have no Neutral point, then this servo motor is not suitable for this connection.
