2.1Arrangements
All protection functionsincluding dc/dc converterare
accommodated on one DoubleEuropa Formatplug-
inmodule.Thismoduleisinstalled in a 7XP20 hous-
ing.Two different typesofhousing can be delivered:
-- 7SV512K--KBKKK-- in housing 7XP2030--1for
panelsurface mounting
The housing hasfull sheet-metalcovers,aswell as
aremovablefrontcoverwithtransparentplastic
window.
Guide railsare builtinforthe supportofplug-in
modules.Onthe top and bottomplatesof the
housing,contactareaswhich are electrically con-
nected tothe housing areinstalled tomatewiththe
earthing springsof the module.Connection to
earthismade beforethe plugsmakecontact.
Earthing screwshave been provided on the left
hand side of the housing.Additionally, terminal16
is connected tothe case.
All externalsignalsareconnected bymeansof60
screwed terminalswhich are arranged overcut-
outson the top and bottomcovers.The terminals
are numbered consecutivelyfromleft torightat the
bottomand top.
The heavy duty currentplug connectorsprovide
automatic shorting of the c.t. circuitswheneverthe
moduleiswithdrawn.Thisdoesnotreleasefrom
the careto be taken when c.t. secondary circuits
areconcerned.
Forthe optional interfaceto a centralcontroland
storage unit, an additionalcoupling facilityhas
been provided.Forthe opticalfibreinterface(mod-
el7SV512K--KKKKK--KC), twoF--SMAconnectors
are provided.
The degree ofprotection forthe housing isIP51,
forthe terminalsIP21.Fordimensionspleaserefer

1A2).The individualconnectionswithin a module
are numbered consecutivelyfromleft toright
