Note:
The unit must be permanently earthed using two independent earth conductors using X1.
Protect the incoming mains supply using a suitable fuse or circuit breaker as shown in
Chapter 11: “Technical Specifications” - Power Details.
Motor Cable Clamp
In order to conform with the specified generic EMC standards, the motor cable must be screened
and the screen connected to both the motor frame and the motor cable clamp. This clamp is
internally connected to power terminals PE (Protective Earth) and provides convenient 360°
connection. It is used for the motor protective earth, motor and control cable screen connections.
Refer to Chapter 12: “Certification for the Servo Drive” for information on meeting generic
EMC standards and minimising electrical interference.
