Selecting the control cables
General rules
It is recommended to use halogen free, shielded control and data cables.
A double-shielded cable is the best alternative for low-voltage digital signals but a
single-shielded twisted pair cable is also usable.
Double-shielded twisted pair cable
Signals in separate cables
Never mix 24 V DC and 115/230 V AC signals in the same cable.
Signals allowed to be run in the same cable
Relay-controlled signals can share the same cables as digital signals, provided that
their voltage does not exceed 48 V. It is recommended to run relay controlled signals
as twisted pairs.
Fieldbus and I2I link signals can share the same cable, provided that the Data +/-
signal conductors run in the same twisted pair and both interfaces have separate
functional ground conductors.
Recommended relay cable type
Cable type with a braided metallic screen (for example, Lapp Kabel ÖLFLEX or
equivalent) has been tested and approved by ABB.
