￭ 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 be longer than
three meters (10 ft). Cable type: shielded CAT 5e or better Ethernet patch cable with RJ-45
ends.
Routing the cables
Route the motor cable away from other cable routes. Cables of several motors can be run
in parallel installed next to each other. The motor cable, input power cable and control cables
should 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, make sure 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. Aluminum tray systems can be used to improve local equalizing of potential.
