Wiring Guidelines
Follow the recommendations in this section to ensure best performance of the SubDrive Utility and
to avoid interference with other devices.
Cable Routing
Use the above diagram as a guide when routing wiring to VFD.
1. Mount the drive as close as possible to the service entrance panel. Wire directly to the service
entrance. Do not connect to a sub-panel.
2. Use a dedicated branch circuit for the drive. Refer to
page
19.
3. Route motor wiring out of building as soon as possible. Separate input power and motor wir-
ing by at least 8 in. (20.3 cm). Refer to
4. Cross over other branch circuits and facility wiring at a 90 angle. If it is necessary to run wir-
ing in parallel, separate by at least 8 in. (20.3 cm).
All control wiring—sensors, switches, transducers, etc.—should be in a separate conduit routed
individually, not parallel, from high voltage wiring. In addition, any shielded cables should be prop-
erly grounded.
