Planning the electrical installation
44
Selecting the control cables
It is recommended that all control cables be shielded.
Double-shielded twisted pair cable is recommended for analogue signals. For pulse
encoder cabling, follow the instructions given by the encoder manufacturer. Use one
individually-shielded pair for each signal. Do not use a common return for different
analogue signals.
Double-shielded cable is the best alternative for low-voltage digital signals but
single-shielded twisted multipair cable (Figure
b
) is also usable.
Run analogue and digital signals in separate 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 VAC signals in the same cable.
Relay cable
The cable type with braided metallic screen (e.g. ÖLFLEX by Lapp Kabel, Germany)
has been tested and approved by ABB.
Control panel cable
The cable connecting the control panel to the drive must not exceed 3 metres in
length. The cable type tested and approved by ABB is used in control panel option
kits.

.
Routing the cables
Route the motor cable away from other cable routes. Motor cables of several drives
can be run in parallel installed next to each other. It is recommended that the motor
cable, input power cable and control cables be installed on separate trays. Avoid
long parallel runs of motor cables with other cables in order to decrease
electromagnetic interference caused by the rapid changes in the drive output
voltage.
