Routing the cables
￭ Guidelines for routing the cables
• Route the motor cable away from other cables.
• Avoid long parallel runs of power cables with other cables. See the allowed minimum
distances below. You can install motor cables of several drives in parallel.
• Install the motor cable, input power cable and control cables on separate trays.
• Make sure that the cable trays have good electrical bonding to each other and to the
grounding electrodes. You can use aluminum tray systems to improve local equalizing
of potential.
• 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.
This figure illustrates the cable routing guidelines with an example drive.
