Note:
1. Cables of the sizes recommended for the main circuit can be used in scenarios where the ambient
temperature is lower than 40° C, the wiring distance is shorter than 100 m, and the current is the rated
current.
2. The terminals P1, (+), and (-) are used to connect to DC reactors and brake accessories.
D.4.3 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.
Aluminum tray systems can be used to improve local equalizing of potential.
A figure of the cable routing is shown below.
