Connecting the power cables and busbars
The circuit diagrams in this section are templates for the final main circuit diagrams. They
do not contain details, such as terminal markings, etc. and are not suitable for the
installation work as such. The designer of the cabinet-installed drive must:
•
prepare the final circuit diagrams
•
provide the final circuit diagrams to the installer(s).
The electricians that do the connections must use the final circuit diagrams.

1)
Fuses or other protection means.
2)
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 modules and other components connect to the cabinet grounding point [PE] via their mounting
bases 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. See section
Connection procedure
on page 103
Notes:
For the cable selection instructions, see Electrical planning instructions for ACS880 multidrive cabinets and
