590 Series DC Digital Drive Installing the Drive
3-37
External AC Supply EMC Filter Installation
Refer to Appendix E: “Technical Specifications” - Environmental Details, and External AC Supply (RFI) Filters and Line Choke for selection details.
A filter is used with the Drive to reduce the line conducted emissions produced by the Drive. Filters are used in parallel on the higher current Drives.
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 Drive with Filter
WARNING
Do not touch filter terminals or cabling for at least 5 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 Drive 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 Drive. 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 Drive next to the filter, allowing for the required air gap between the Drive, the filter and any adjacent equipment.
NOTE When filters CO389456 are mounted in parallel, they should be spaced 40mm apart for ventilation
Connection Details
The connection between the Drive, choke and filter must always be as short as possible and must be segregated from all other cables. Ideally, mount
the filter and choke onto the same metallic panel as the Drive. Take care not to obstruct any ventilation spacing.
If this cable/busbar exceeds 0.6m (2 feet) in length, it must be replaced with a screened/armoured cable. The screen/armour must be earthed at both the
filter, choke and Drive ends with large-area contact surfaces, preferably with metal cable glands.
