14The 4 pole pushbutton contact can be addedwith the standard CCH actuators.If the 4 pole pushbutton contact is added withan Emergency STOP Mushroom-headpushbutton actuator, then you have to use theactuators with CCH order numberGHG 410 1437R.This actuators can be recognized by the redthrust washer and black inserting sign.a The data according to sections 3 and 4shall be taken into account during use.a Applications other than those describedare not permissible without a writtendeclaration of consent from Messrs.COOPER Crouse-Hinds.a During operation the instructions statedin section 7 of the operating instructionsshall be observed.a The sole responsibility with respect tothe suitability and proper use of the controlswitches with regard to the basic require-ments of these instructions (see technicaldata) lies with the operator.6 InstallationThe relevant national regulations (e.g. Betr.Si.V,the equipment safety law for Germany) andthe generally recognized rules of engineeringapply for the installation and operationIEC/EN 60079-14.a The improper installation and operationof control switches may result in theinvalidation of the guarantee.6.1 MountingThe control units GHG 411 can be mountedwithout opening the enclosure.When the control units are mounted directlyonto the wall, they shall rest evenly only on thefastening points provided for this purpose.The screw chosen shall fit the fixing hole (seedimensional drawings, page 10) and shall notdamage the hole (e.g. use of a washer).The apparatus shall be fixed diagonally with aminimum of 2 screws.a If the screws are overtightened, theapparatus may be damaged.The control units GHG 411 and GHG 412 aresuited for mounting on CEAG apparatus holdersby means of self-cutting screws (see pages 16).See the respective mounting instructions.The control units GHG 412 can be mounted inthe flange openings provided for this purpose(see page 10).Here special attention shall be paid to an evensealing surface and the perfect condition of theseal that is foamed into the enclosure cover ofthe control unit.The control unit is mounted in the flangeopening by means of fixing lugs that engagebehind the flange opening.These are actuated by turning the 2 fixingscrews on the front of the enclosure coverclockwise.6.2 Opening apparatus/Electrical connectiona Before opening the apparatus, it isnecessary to ensure that there is no voltageor to take suitable protective measures.a The electrical connection of the may onlybe carried out by specialists.(IEC/EN 60079-14)The properly bared conductors of cables shallbe connected with due regard to the respectiveregulations.If multi- or fine-wire connection cables areused, the wire ends shall be handled accordingto the applicable national and internationalregulations (e.g. use of multicore cable ends).a To maintain the explosion protection,conductors shall be connected with specialcare.The insulation shall reach up to theterminal. The conductor itself shall not bedamaged.a In the case of mixed Ex-e / Ex-i installa-tions, the required minimum clearancesshall be maintained (see, for example,IEC/EN 60079-11).When apparatus is open, itis necessary to ensure (disconnect voltagesupply) that no voltage is carried over intothe connected intrinsically safe circuits.The installation instructions for intrinsically safeelectrical apparatus shall be observed.It is necessary to ensure that the permissibleexternal capacitance and inductance of thespecial intrinsically safe circuits are notexceeded.The minimum and maximum conductor crosssections that can be connected shall beobserved (see technical data).Actuator 1 x 4 poleActuator 2 x 2 poleMushroom-head pushbutton actuator"EMERGENCY STOP" GHG 410 1437R....2122 4443R1343311124443R23433242314132122R31112414231324443R43433242311122122R511123132 4443S 1S 2S 4S 3S 2S 4S 3S4S 12122 4443R1343311124443R23433242314132122R31112414231324443R43433242311122122R511123132 4443S2 S3S1thrust washerredinserting signblackbaseyellowS4S2 S3S1EExplosion-protected control unitsGHG 411 and 412
