100 Guidelines for planning the electrical installation
Selecting the control cables, IEC and North America

Shielding
All control cables must be shielded.
Use a double-shielded twisted pair cable (figure a below) for analog signals. Employ
one individually shielded pair for each signal. Do not use common return for different
analog signals.
A double-shielded cable is the best alternative for low-voltage digital signals but
single-shielded (b) twisted pair cable 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 allowed to be run in the same cable
Relay-controlled signals, providing their voltage does not exceed 48 V, 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) has been tested and approved by the manufacturer.

Control panel cable
In remote use, the cable connecting the control panel to the drive must not exceed
100 m (330 ft). If multiple drives are connected, the total length of the panel bus must
not exceed 100 m (330 ft).
The cable type tested and approved by the manufacturer is used in control panel
option kits. Suitable cables are CAT 5e unshielded or shielded twisted pair cables.
