Design
The electrical components are incorporated in an RF-tight case of stainless steel. The cables enter
through glands. The RF-tight termination of the openings is produced by specially shaped lids.
The conductors and equipment grounding conductor are connected by threaded bolts. The space
around the fixing holes is left as bare metal (unpainted) to ensure good RF contact with metal sur-
faces (chassis, ground).
Protective measures (grounding)
The high capacitances between the lines and ground require special protective measures. If there
are no product-specific requirements, protection with a secondary ground wire (diameter min.
10 mm
2
) in accordance with EN 50178 is necessary. For this purpose the filter case have connect-
ing bolts at each end.
Resistors are incorporated in the filter to discharge capacitors after turn-off.
Installation
Filters are supplied complete with all parts required for RF-tight installation (fixing screws, flanges,
RF gaskets, cable glands) and installation instructions.
No welding is needed on the shielding wall, so any subsequent installation is quite simple. And the
uniform template of the attachment points allows straightforward replacement of a two-line filter by
a four-line filter for example.
Accessories and special versions
RF-tight flexible connector fittings in widths of 25 and 40 mm are available for installation spaced
away from the shielding wall.
Filters with an EMP protection add-on for surge currents up to 100 kA per line are available on
request.
To match requirements, filters can be supplied with different kinds of EMC or shielding cable glands.
Tests
All filters are 100 % tested and the results are archived under a filter’s serial number. If required, a
test report can be generated for the serial number.
