￭ Additional guidelines, North America
ABB recommends the use of conduit for power wiring to the drive and between the drive
and the motor(s). Due to the variety of application needs, metallic and non-metallic conduit
can be used. ABB prefers the use of metallic conduit.
The following table shows examples of various materials and methods for wiring the drive
in the intended application. See NEC 70 along with state and local codes for the appropriate
materials for your application.
In all applications, ABB prefers the use of symmetrical shielded VFD cable between drive
and motor(s).
Notes Wiring 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.
