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. 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.

Separate control cable ducts


Lead 24 V and 230 V (120 V) control cables in separate ducts unless the 24 V cable is
insulated for 230 V (120 V) or insulated with an insulation sleeving for 230 V (120 V).
