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 are installed on separate trays. Avoid
long parallel runs of motor cables with other cables to decrease electromagnetic
interference caused by the rapid changes in the drive output voltage.
Where control cables must cross power cables make sure that they are arranged at
an angle as near to 90 degrees as possible.
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.
