￭ 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).

Conduit - Metallic
1) 2)
• Use separate conduit run for each motor.
• Do not run power feed wiring and motor wiring in the
same conduit.
Electrical metallic tubing: Type EMT
Rigid metal conduit: Type RMC
Liquid-tight flexible metal electrical conduit: Type LFMC
Conduit - Non-metallic

3)
• Use separate conduit run for each motor.
• Do not run power feed wiring and motor wiring in the
same conduit.
Liquid-tight flexible non-metallic conduit: Type LFNC

2)
• Use output conductors require separation from motor
feed and other low voltage conductors.
• Do not run outputs of multiple drives in parallel.
Bundle each cable together and use separator where
possible.
