Power feedback units are electrical units for usage in industrial and commercial
plants. In accordance with the EMC guideline 89/336/EEC 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 an 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 carried out by the erector / user of the ma-
chine / plant. If the by ELTROPLAN-REVCON released RFI-filters are used
and the following measures and installation guidelines are observed, the adher-
ence to the prescribed data is cleared.
In combination with the related RFI-filter the power feedback unit has been de-
signed for the usage in ambients of the limit class „A“ („B“ on request).

Installation
Appropriate design of pant and cabinet.
To avoid noise incoupling 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 metal-
lic connections (e. g. mounting plates, mounted units) have to be done with a as
big as possible surface to metallic ground. Use grounding and potential equali-
sation wires with as big cross section as possible (min. 10mm²) or thick
grounding tapes.
