▪ For signal transmission, use shielded lines with individual conductors (out-
going conductor / return conductor) twisted in pairs.
▪ Connect full surface of shielding (360º) to device or to a nearby grounding
bar.
Using single conductors may limit the effectiveness of the shielding. Con-
nect close-fitting shielding to cover all areas.

6.4.5.3 Wiring requirement in control cabinet
Note the following when wiring the control cabinet:
▪ The control cabinet where the device will be installed must be prepared in
accordance with EMC requirements:
– Functional division of control cabinet (physical separation)
– Constant potential equalization (all metal parts are joined)
– Line routing in accordance with EMC requirements (separation of lines
which cause interference and those susceptible to interference)
– Optimum shielding (metal housing)
– Overvoltage protection (lightning protection)
– Collective grounding (main grounding rail)
– Cable bushings in accordance with EMC requirements
– Any contactor coils present must be interconnected
▪ The device's connection cables must be laid in close contact with the
grounded metal housing or in metallic cable ducts with a ground connec-
tion.
▪ Signal lines and power lines/switching lines must be laid in separate cable
ducts.
