Selecting The Control Cables; Relay Cable; Control Panel Cable - ABB ACS800-04 Hardware Manual

Selecting the control cables

All control cables must be shielded.
Use a double-shielded twisted pair cable (Figure a, e.g. JAMAK by NK Cables,
Finland) for analogue signals. This type of cable is recommended for the pulse
encoder signals also. Employ one individually shielded pair for each signal. Do not
use common return for different analogue signals.
A double-shielded cable is the best alternative for low-voltage digital signals but
single-shielded twisted pair cable (Figure b) is also usable.
Run analogue and digital signals in separate, shielded cables.
Relay-controlled signals, providing their voltage does not exceed 48 V, can be run in
the same cables as digital input signals. It is recommended that the relay-controlled
signals be run as twisted pairs.
Never mix 24 VDC and 115/230 V AC signals in the same cable.

Relay cable

The cable type with braided metallic screen (e.g. ÖLFLEX by LAPPKABEL,
Germany) has been tested and approved by ABB.

Control panel cable

In remote use, the cable connecting the control panel to the drive must not exceed 3
metres (10 ft). The cable type tested and approved by ABB is used in control panel
option kits.
