External AC Supply EMC Filter Installation
Refer to Chapter 11: “Technical Specifications” - Environmental Details, and External AC
Supply (RFI) Filters and Line Choke for selection details.
A filter is used with the Converter to reduce the line conducted emissions produced by the
Converter. Filters are used in parallel on the higher current Converters. When installed correctly
and used with the specified 2% minimum line chokes, conformance with EN55011 Class A can
be achieved (suitable for both generic environments: RF Emission and Immunity).
Cubicle-Mounting the 590 Converter with Filter
WARNING!
Do not touch filter terminals or cabling for at least 3 minutes after removing the
ac supply.
The CO389456 filter flying leads can reach 100°C under normal operating
conditions. Leads should be separated to at least one cable diameter and adequately
ventilated. Never bunch leads together.
Only use the ac supply filter with a permanent earth connection.
The filter should be fitted on the mains side of the contactor.
The Converter must be mounted vertically on a solid, flat, vertical surface. It must be installed
into a cubicle.
The recommended EMC filter is mounted to the left, right, above, below, or spaced behind the
Converter. It can be mounted flat against the surface, or projecting out from the surface if the
filter type has side fixings.
1. Mount the filter securely at the four fixing points (flat or on its side).
2. Mount the Converter next to the filter, allowing for the required airgap between the
Converter, the filter and any adjacent equipment.
Note:
When filters CO389456 are mounted in parallel, they should be spaced 40mm apart for
ventilation.
