Additional guidelines – North America
ABB recommends the use of metallic conduit for power wiring. ABB also
recommends the use of symmetrical shielded VFD cable between drive and
motor(s).
This table shows examples of methods for wiring the drive. Refer to NFPA 70 (NEC)
along with state and local codes for the appropriate methods for your application.
NotesWiring method
Conduit - Metallic
1) 2)
Prefer symmetrical shielded VFD cable.
Electrical metallic tubing: Type EMT
Use separate conduit run for each motor.Rigid metal conduit: Type RMC
Do not run input power wiring and motor
wiring in the same conduit.
Liquid-tight flexible metal electrical conduit:
Type LFMC
Conduit - Non-metallic
2) 3)
Prefer symmetrical shielded VFD cable.
Liquid-tight flexible non-metallic conduit:
Type LFNC
Use separate conduit run for each motor.
Do not run input power wiring and motor
wiring in the same conduit.
Wireways
2)
Prefer symmetrical shielded VFD cable.
Metallic
Separate motor wiring from input power
wiring and other low voltage wiring.
Do not run outputs of multiple drives parallel.
Bundle each cable (wiring) together and use
separators where possible.
