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 in-lb) for frame sizes R0…R2, 1.7 N·m
(15 in-lb) for R3, and 2.5 N·m (22 in-lb) 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 in-lb) for frame sizes R0…R2, 1.7 N·m (15 in-lb) for R3, and 2.5 N·m (22 in-lb)
for R4.
3. Secure the cables outside the drive mechanically.
