Operating
Instructions
To comply with EMC directives – corresponding to
EN 50081-1 and EN 50082-2 – RESISTRON and
CIRUS control loops must be operated with
interference suppression filters.
The use of a suitable line filter is part of the
standards conformity and a prerequisite of
the CE mark.
These filters damp the reaction of the phase-angle
control on the line and protect the controller against
system disturbances.
ROPEX line filters are specially optimized for use in
RESISTRON and CIRUS control loops. Providing they
are installed and wired correctly, they guarantee
compliance with the EMC limit values.
Please do not hesitate to contact us if you require
design support for applications that are susceptible to
extreme loads.

Installation steps
Installation and startup may only be
performed by suitably trained persons who
are familiar with the associated risks and warranty
provisions.
1. Disconnect the supply voltage.
2. Screw the line filter onto a galvanized mounting
plate, using sufficient screws to make contact over a
large area.
3. Connect the mounting plate to ground potential by
means of a grounding cable (crosssection
4. The connecting cable to the control loop on the
output side must not be longer than 1.0m, nor must
it intersect any other current-conducting cables.
25mm², max. 1.5m long).
Dimensions
5. The input and output wires of the line filter must not
be laid parallel.
6. Please comply with the wiring installation procedure
described in the relevant controller documentation
( "Installation procedure" and "Startup and
operation" sections).
It is permissible to supply several
RESISTRON or CIRUS control loops with a
single filter, providing the total current does not
exceed the maximum current of the filter.
The parallel installation of two filters (same
type) is permissible when the connecting
cables are installed symmetrically. The total current shall not exceed the double maximum current
of one filter.
