1.
Remove cable sheathing.
2.
Insert the wire into the cable glands.
3.
Fasten cable gland with the specified torque to ensure required enclosure pro-
tection.
4.
Remove wire sheathing in a length of approx. 6 mm.
5.
For flexible cables: Use 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 at socket carrier using ring lugs
(flexible cables) or loops (solid cables).
8.
Connect equipotential earth bonding at external earth connection for equipoten-
tial compensation (U-bracket with symbol )

For fine stranded (flexible) wires, connection is made via cable lugs/ring terminals. When connecting
two individual wires with a U-bracket, cross sections have to be identical.
