Selecting the control cables



Shielding

Only use shielded control cables.
Use a double-shielded twisted pair cable (a) for analog signals. Use one individually
shielded pair for each signal. Do not use a common return for different analog
signals.
A double-shielded cable (a) is the best alternative for low-voltage digital signals, but a
single-shielded (b) twisted pair cable is acceptable.


Signals in separate cables

Put analog and digital signals in separate, shielded cables.
Do not mix 24 V 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 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) has been tested and approved by ABB.


Drive composer PC tool cable

Use a USB type A (PC) – type B (control panel) cable. The maximum permitted
length of the cable is 3 m (9.8 ft).
