• Do not run extra cables through the drive.
• Make sure that 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.
The following figure illustrates the cable routing guidelines with an example drive.
Note: When motor cable is symmetrical and shielded and it has short parallel runs
with other cables (< 1.5 m / 5 ft), distances between the motor cable and other
cables can be reduced by half.

General guidelines – North America
Make sure that the installation is in accordance with national and local codes. Obey
these general guidelines:
• Use separate conduits for the input power, motor, brake resistor (optional),
and control cabling.
• Use separate conduit for each motor cabling.
