Planning the electrical installation 53

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. It is recommended that the relay-controlled signals be
run as twisted pairs.

Relay cable type
The cable type with braided metallic screen (for example ÖLFLEX by LAPPKABEL,
Germany) has been tested and approved by ABB.

Control panel cable length and type
In remote use, the cable connecting the control panel to the drive must not exceed 3
meters (10 ft). 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.
Where control cables must cross power cables ensure that they are arranged at an angle
as near to 90 degrees as possible. Do not run extra cables through the drive.
The cable trays must have good electrical bonding to each other and to the grounding
electrodes. Aluminium tray systems can be used to improve local equalizing of potential.
A diagram of the cable routing is shown below.
