To connect the power cables at the connection plug, prepare these as subsequently
described:
1. Remove the cable sheath to a length of 85 mm (3.35 in) with a tolerance of ±5 mm (±0.2 in).
2. Shorten the protective braided shield and fold it back by the same length.
– If you use a motor connection cable with brake cores, then you must unbraid the
protective braided shield of the brake cores. This is then folded back against the outer
shield.
3. Fix the protective braided shield. Preferably use a shrink-on sleeve with hot melt adhesive.
