Screw the cable glands on the cable entry holes.

•
Pass the cables (supply cable, motor cable, brake cable and I/O cables)
through the cable glands.
7
•
Detach the cable clamps and the grounding clamps.

Connect the stripped cables:
•
Expose the shield of the motor cable in order to make a 360-degree con-
nection with the cable clamp (reverse the shield over the plastic cover of
the cable and fix all together).
•
Connect the phase conductors of the supply and motor cables into their
respective terminals.
•
Form the rest of the cable shield of all two cables into “pigtails” and make
a grounding connection with the clamp. Make the pigtails just long enough
to reach and be fixed to the terminal - no longer.
