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, electric shock due to presence of hazardous voltage if the
PE conductor is NOT connected!
Risk of death or serious injury!
→
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.
