Guidelines for electrical installation

General Notes

General

Cables should be grouped together, for example: signal cables, data cables, heavy current
cables, power supply cables.
Heavy current cables and signal or data cables should always be routed in separate cable
ducts or bundles. Signal and data cables must always be routed as close as possible to
ground potential surfaces (for example support bars, cabinet sides etc.).

Cable routing

Correct cable routing prevents or suppresses the reciprocal influencing of parallel routed
cables.

Cable routing inside and outside of cabinets

To ensure EMC-compatible cable routing, the cables should be grouped as follows:
Group 1:
shielded bus and data cables
shielded analog cables
unshielded cables for DC voltage ≤ 60 V
unshielded cables for AC voltage ≤ 25 V
Group 2:
unshielded cables for DC voltage > 60 V and ≤ 400 V
unshielded cables for AC voltage > 25 V and ≤ 400 V
Group 3:
unshielded cables for DC and AC voltages > 400 V
The following group combination can be routed only in separate bundles or separate cable
ducts (no minimum distance apart):
Group 1/group 2
The group combinations:
Group 1/group 3 and group 2/group 3
must be routed in separate cable ducts with a minimum distance of 10 cm apart. This is
equally valid for inside buildings as well as for inside and outside of switchgear cabinets.

Cable routing outside buildings

Outside of buildings, cables should be routed in closed (where possible), cage-type cable
ducts made of metal. The cable duct joints must be electrically connected and the cable ducts
must be earthed.
6-2
Warning
Observe all valid guidelines concerning internal and external lightning protection
and grounding specifications when routing cables outside of buildings.
