64 Planning the electrical installation
Routing the cables

General rules
• Route the motor cable away from other cables. The motor cables of several drives
can be put in parallel next to each other.
• Install the motor cable, input power cable and control cables 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 they are arranged at
an angle as near to 90 degrees as possible.
• Do not run extra cables through the drive.
• Make sure the cable trays have good electrical bonding to each other and to the
grounding electrodes. Aluminum tray systems can be used to improve local
equalizing of potential.
