1. Remove cable sheathing in a length of 250 – 300 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:
4.1 Remove wire sheathing of control cables (1...50) in a length of approx. 10
mm
4.2 Remove wire sheathing of motor cables (U, V, W) in a length of approx.
12 mm
5. For flexible cables: Use wire end sleeves according to DIN 46228. For push-in
terminal, connection is also possible without wire end sleeves.
Information: For two flexible wires per terminal, a joint wire end sleeve must
be used.
6. Connect cables according to order-related wiring diagram.
