3. Connect the motor cable as follows:
• Ground the shield 360 degrees by tightening the clamp of the power cable grounding
shelf onto the stripped part of the cable (3a).
• Connect the twisted shield of the cable to the grounding terminal (3b).
• Connect the phase conductors of the cable to the terminals of T1/U, T2/V and T3/W.
