1. Remove cable sheathing in a length of 120
2. Insert the wires into the cable glands.
3. Fasten cable glands with the specified torque to ensure required enclosure
protection.
Information: For shielded cables: Link the cable shield end via the cable gland
to the housing (earthing).
4. Strip wires.
Controls max. 8 mm, motor 12 mm
5. For flexible cables: Use wire end sleeves according to DIN 46228.
6. Connect cables according to order-related wiring diagram.
Information: Two wires for each connection permitted.
When using motor cables with wire cross section of 1.5 mm²: Use small
clamp washers for connection to terminals U1, V1, W1 and PE (the small
clamp washers are in the cover of electrical connection upon delivery).
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. Firmly tighten protective earth to PE connection.
