18 VIX AE SERVO DRIVE USER GUIDEPL1100 EMC Installation Guidelines
These EMC installation recommendations are based on the expertise acquired during the
development of compliant applications, which Parker believes are typical of the way, a
PL1100 may be used. Provided you have no special installation requirements or untypical
operating environment requirements, PL1100 power supplies will conform to current EMC
Directives.
If you are using the recommended transformers (TO255 & TO256) both primaries can be fed
from a single EMC filter. Use a CORCOM 12FC10 or its equivalent. See Figure 3-5.
Mount the supply on a conductive panel to which the EMC filter and the drive(s) are also
attached. If the panel has a paint finish, it will be necessary to remove the paint in certain
areas to ensure the filter and supply, make a good large-area metal to metal contact with the
panel.
Position the PL1100 as close as possible to the drives it is to supply (less than one metre).
Ideally, the EMC filter needs to be close to the transformers, which in turn, should be as
close to the PL1100 as can be arranged. Assuming the use of an equipment cabinet, locate
the EMC filter and transformers in the base of the cabinet and route AC supply cables up to
the PL1100. Attempt to layout the wiring in a way that minimises cross coupling between
filtered and non-filtered conductors. This means avoiding running wires from the output of a
filter close to those connected to its input. Where you wish to minimise the cross coupling
between wires avoid running them side-by-side one another, if they must cross, cross them
at 90° to each other. Keep wiring supported and close to cabinet metalwork.
