Clearances from the RFI filter and AC
supply cables
1.
Mount the RFI filter as close as
possible to the drive. No
clearance is required either
side of the RFI filter or the
drive.
2.
Make the wires connecting the
RFI filter to the drive as short
as possible.
3.
Allow at least 100mm (4 in)
clearance (C) between the AC
supply cable and the following:
• Signal cables
• Drive
• Braking resistors and cables
• Motors and cables

Additional ground connections for
the signal cables
Electrically bond the shields of all the signal cables to the back-plate by
direct grounding unless ground-loop currents cause problems if the drive
is controlled by an analog speed reference. In this case, indirect
grounding can be used to ground all the cables except the cable
connected to the SIM ENC connector; this must always be directly
grounded.
Refer to the next two diagrams.
