Connection procedure
1. Fasten the grounding conductor (PE) of the input power cable under the
grounding clamp. Connect the phase conductors to the U1, V1 and W1 terminals.
Use a tightening torque of 0.8 N·m (7 lbf·in) for frame sizes R0…R2, 1.7 N·m
(15 lbf·in) for R3, and 2.5 N·m (22 lbf·in) for R4.
2. Strip the motor cable and twist the shield to form as short a pigtail as possible.
Fasten the twisted shield under the grounding clamp. Connect the phase
conductors to the U2, V2 and W2 terminals. Use a tightening torque of 0.8 N·m
(7 lbf·in) for frame sizes R0…R2, 1.7 N·m (15 lbf·in) for R3, and 2.5 N·m
(22 lbf·in) for R4.
3. Secure the cables outside the drive mechanically.
