Power feedback units are electrical units for usage in industrial and commercial plants.
In accordance with the EMC guideline 2004/108/EG it is not obligate to mark these
units, as in the sense of the EMC guideline and the EMC law they are components to be
mounted by a competent electromechanical engineer and cannot be used stand alone.
The proof of the observance of the protective aims of the EMC guideline has to be car-
ried out by the erector / user of the machine / plant. If the by ELTROPLAN-REVCON
released RFI-filters are used and the following measures and installation guidelines are
observed, the adherence to the prescribed data is cleared.
In combination with the related RFI-filter the power feedback unit has been designed
for the usage in ambients of the limit class „A“ („B“ on request).
Definition in accordance with basic standard:
•
Electromagnetic compatibility (EMC) - Part 6-4: EN 61000-6-4 and IEC
61000-6-4:2006 Generic standards-Emission standard for industrial environments.
•
Electromagnetic compatibility (EMC) - Part 6-2: EN 61000-6-2 and IEC 61000-6-2
Generic standards- Immunity for industrial environments.

Installation
Appropriate design of pant and cabinet:
To avoid noise in coupling lay
a) mains/supply wires
b) motor wires of controllers / servo amplifiers
c) control- and data wires (small voltage range < 48 V) with a distance of at least 15 cm
between each other.
To obtain low resistive HF-connections, grounding, screening and other metallic con-
nections (e. g. mounting plates, mounted units) have to be done with a as big as possible
surface to metallic ground. Use grounding and potential equalisation wires with as big
cross section as possible (min. 10mm²) or thick grounding tapes.
