How to proceed
1. Loosen screws [2] and remove cover [1].
2. Insert cable glands suitable for connecting cables.
3. Seal unused cable entries with approved plugs suitable for the required protec-
tion type.

1. Remove cable sheathing in a length of 120 – 140 mm.
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.
