62 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 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) was tested and approved by ABB.

Control panel cable
In remote use, the cable connecting the control panel to the drive must not exceed
100 m (330 ft). If multiple panels or drives are connected, the total length of the panel
bus must not exceed 100 m (330 ft).
The cable type tested and approved by ABB is used in control panel option kits.
Suitable cables are CAT 5e unshielded or shielded twisted pair cables.
