Installing the Drive
DC590+ Series DC Digital Drive
External AC Supply EMC Filter Installation
Refer to Appendix E: “Technical Specifications” - Environmental Details, and External AC Supply (RFI) Filters, and AC 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 DC590+ Drive with Filter
WARNING
Do not touch filter terminals or cabling for at least 5 minutes after removing the ac supply.
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.
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.
You should enhance the RF connection between the Drive, choke, filter and panel as follows:
1.
Remove any paint/insulation between the mounting points of the EMC filter, choke, Drive and the panel. Liberally apply petroleum jelly over the
mounting points and securing threads. This will prevent corrosion. Alternatively, conducting paint could be used on the panel.
2.
If
1
above is not possible, then improve the RF earth bond between the filter and Drive by making an additional RF earth connection. Use wire
braid of at least 10mm
²
cross-sectional area.
