Principles of entering and laying cables
Lead in permanently laid entries using EMC cable glands. Screw the cable glands
into the threaded holes in the unscrewable entry plate.
Arrange the exposed connecting cables in the terminal box such that the PE
conductor has excess length and the insulation of the cable strands cannot be
damaged.
Note
We recommend you use shielded cables, whose shields are conductively
connected to a large area of the metal terminal box of the motor (with an EMC
cable gland made of metal).
Notice
Unused threads must be sealed with a metallic screw plug.
