1. Remove cable sheathing.
2. Insert the wires into the cable glands.
3. Fasten cable glands with the specified torque to ensure required enclosure
protection.
4. Strip wires.

Controls approx. 6 mm, motor approx. 10 mm
5. For flexible cables: Use wire end sleeves according to DIN 46228.
6. Connect cables according to order-related wiring diagram.
In case of a fault: Hazardous voltage while protective earth conductor is NOT
connected!
Risk of electric shock.
→
Connect all protective earth conductors.
→
Connect PE connection to external protective earth conductor of connecting
cables.
→
Start running the device only after having connected the protective earth con-
ductor.
7. Tighten PE conductors firmly to PE connection using ring lugs (flexible cables)
or loops (solid cables).
