Routing The Cables; Control Cable Ducts - ABB ACS800-04 Hardware Manual

62 Planning the electrical installation

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 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.
