54 Planning the electrical installation
Selecting the control cables
Shielding
Use only shielded control cables.
Use a double-shielded twisted pair cable (figure
a
below) for analog signals. Use one
individually shielded pair for each signal. Do not use common return for different
analog signals.
A double-shielded cable (figure
a
) is the best alternative for low-voltage digital signals
but a single-shielded twisted pair cable (figure
b
) is also acceptable.
Signals in separate cables
Run analog and digital signals in separate, shielded cables.
Do not mix 24 V AC/DC and 115/230 V AC signals in the same cable.
Signals that can be run in the same cable
If their voltage does not exceed 48 V, relay-controlled signals can be run in the same
cables as digital input signals. The relay-controlled signals should be run as twisted
pairs.
Relay cable
The cable type with braided metallic screen (for example ÖLFLEX by LAPPKABEL,
Germany) is tested and approved by ABB.
