Figure 22: Recommended wiring
1 Cable duct for lines causing interfer-
ence
2 Line causing interference (e.g. power
line)
– Short-circuit and ground reserve lines.
– Never connect the device with a multi-wire collective pipe.
– For signal transmission, use shielded lines with individual conductors (outgo-
ing 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-
i
nect close-fitting shielding to cover all areas.

5.4.2.3 Wiring requirement in control cabinet
Note the following when wiring in the control cabinet:
– The control cabinet where the device will be installed must be prepared in ac-
cordance with EMC requirements:
– Functional division of the control cabinet (physical separation)
– Constant potential equalization (all metal parts are joined)
