Motor cable with earthed connection by means of
Faston socket and 360° shield connection on
earthed collar
IMPORTANT
: The motor cable must be shielded and connected over 360° on collars mounted for this purpose on
the housing. The earth wire of the motor cable MUST be connected to the Faston socket marked with the GND
sign.
The earth reference must also be connected on the second Faston socket.
The installer of the drives has to use a UL Listed Quick connect for ground connection (0.250 inches or 6.35
mm wide nominal).
Field wiring terminals have to use copper conductors only.
Torque value for field wiring terminals: value to be according to the Recognized terminal block used.
