64 Planning the electrical installation
Routing the cables
General rules
Route the motor cable away from other cable routes. Motor cables of several drives
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.
A diagram of the cable routing is shown below.
