C.4.4 Grounding the Drive/Filter Assembly
Connect the drive/filter assembly to earth ground at the terminal provided next to the
filter’s AC input power terminals. The ground wire should be sized per EN-60204-1,
Part 5.2
1
,
for copper conductors and EN-60204-1, Part 8.2.2.2
2
, for non-copper
conductors. European Union standards require that the ground wire must be
green/yellow according to EN-60204-1, Part 15.2.2.

EN-60204-1, Part 8.2.2.2: Protective Conductors
Copper conductor should be used. If a material other than copper is used, its electrical
resistance per unit length should not exceed that of copper. Non-copper conductors
should not be less than 16 mm

EN-60204-1, Part 15.2.2: Identification of the Protective Conductor
For insulated conductors, the two-color combination of Green and Yellow should meet
the following criteria for any given 15 mm length: one of the colors should cover at
least 30% and no more than 70% of the surface, with the other color covering the
remainder of the surface.
