KEB combivert R6-S User Manual

4.4 EMC instructions
COMBIVERT R6-S represent electrical equipment designed for use in industrial and com-
mercial units.
In accordance with the EMC directive 2014/30/EU, these devices are with the meaning of the
directive components to be further processed by the respective machine and unit manufac-
turer and are not operable independently.
The person installing / operating the machine / unit is obliged to proove the protective meas-
ures demanded by the EMC directive are complied with. The prescribed ratings can usually
becompliedwithwhenusingtheradiointerferencevoltageltersspeciedbyKEBandwhen
observing the following measures and installation guidelines.
4.5 EMC conform installation
TheCOMBIVERTR6isdesignedtobeusedinthesecondenvironmentasdenedinEN
61800-3(unitwithitsownsupplytransformer).Takeadditionalltermeasureswhenusing
itintherstenvironment(residentialandcommercialareaconnectedtopubliclow-voltage
mains)!
• Installthecontrolcabinetorsysteminanappropriateandcorrectlyway(seechapter„EMC
conformcontrolcabinetinstallation“).
• To avoid coupled-in noises, separate supply lines, DC lines, motor lines, control and data
lines(low-voltagelevel<48V)andleaveaspaceofatleast15cmbetweenthemwhen
installing.
• In order to maintain low-resistance high frequency connections, earthing and shielding, as
wellasothermetallicconnections(e.g.mountingplate,installedunits)mustbeinmetal-
to-metal contact with the mounting plate, over as large an area as possible. Make ground
connectionswithasurfaceaslargeaspossible(earthingstrips).
• Only use shielded cable with copper or tin-plated braid, since steel braid is not suitable for
high frequency ranges. The screen must always be installed on the compensating rail and
fastened with clips or guided through the wall of the housing. Do not elongate the screen
end(pigtails)withindividualconductors!
• Ifexternalinterferencesuppressionltersareused,thenthesemustbeinstalledasclose
aspossibleto(<30cmfrom)theinterferencesourceandinmetal-to-metalcontactwiththe
mouting plate, over as large an area as possible.
• Alwaysequipinductivecontrolelements(contactors,relaysetc.)withsuppressorssuchas
varistors, RC-elements or damping diodes.
• All connections must be kept as short as possible and as close as possible to the earth, as
freeoatinglinesworkasactiveandpassiveaerials.
• Keepconnectioncablesstraight(donotbundle).Installanon-assignedwireatonesidesto
the protective earth conductor.
• Theow and return circuitmustbetwistedwhenthelines are not shielded,inorderto
dampen common-mode noise.
• The cable for phase synchronization between mains choke and COMBIVERT R6-S may
not exceed a cable length of 1 m.
• Furtherinformationcanbefoundintheinternet,see„www.keb.de“.
