ABB ACS355-01E-06A7-2 [21/76] Connection procedure

Quick start-up 21

 Connection procedure

1. Strip the input power cable. Ground the bare shield of the cable (if any) 360 degrees

under the grounding clamp. Fasten the grounding conductor (PE) of the input power

cable under the screw of the grounding clamp. Connect the phase conductors to the

U1, V1 and W1 terminals.

2. Strip the motor cable. Ground the bare shield of the cable 360 degrees under the

grounding clamp. Twist the shield to form as short a pigtail as possible and fasten it

under the screw of the grounding clamp. Connect the phase conductors to the U2, V2

and W2 terminals.

3. Connect DC input to the BRK+ and BRK- terminals with a shielded cable using the

same procedure as for the motor cable.

4. Secure the cables outside the drive mechanically.
