Ground the cable shield 360 degrees at the cable lead-through (recommendation). See section Connection
procedure on page 103 .
3)
Use a separate PE conductor in addition to the input cable shield if the conductivity of the shield does not
meet the requirement for the PE conductor. See Electrical planning instructions for ACS880 multidrive cabinets
and modules (3AUA0000102324 [English]).
4)
The supply module frames and other components connect to the cabinet grounding point [PE] via the
assembly plate and frame of the cabinet. Make sure that there are good electrical contacts (bare metal to
metal, no paint or dirt). Use separate grounding wires in addition where necessary.
Notes:
For the cable selection instructions, see Electrical planning instructions for ACS880 multidrive cabinets and
