9The user alone is responsible for the appropriate use of this plug and socket system.After a short in the circuit, the operativeness has to be checked.The data as per point 3 and 4 will have tobe taken into account with the use.Applications other than described are notpermitted without CCH / CEAG’s priorwritten consent.For the operation, the instructions stated insection 7 of the operating instructions willhave to be observed.In the open air, the plugs must be kept with theplug opening (pin side) pointing downwards orbe closed with protective plug caps available asan optional extra (see general catalogue).6 InstallationFor the mounting and operation, therespective national regulations as wellas the general rules of engineering will haveto be observed.6.1 MountingThe wall sockets can be mounted withoutopening their enclosure.In case the wall sockets are mounted directlyonto the wall, they may rest evenly only at therespective fastening points. The chosen screwshall match the fastening hole (see dimensionaldrawing) and it must not damage the hole(e. g. use of a washer).The device shall be fastened diagonally with atleast 2 screws.The wall sockets and flange sockets shallbe mounted so that the plug hole does notpoint upwards.The wall sockets can be clipped onto the CCH /CEAG mounting plate size 4. They are laterallypushed into the guiding groove on the left-handside of the mounting plate.The respective mounting instructions will haveto be observed.6.2 Opening the device/Electrical connectionThe electrical connection of the device mayonly be carried out by skilled staff.The insulation of the conductors shallreach up to the terminal. The conductoritself shall not be damaged.Taking into account the respective regulations,the properly bared conductors of the cablesshall be connected.The electrical connection of the plugs isestablished as shown in fig. 4 and 5:The plug insert (item 2, fig. 5) is removed fromthe pin bushing (item 1, fig. 5), after thefastening screws (item 3, fig. 4) have beenunscrewed. Thereafter, the plug insert can beconnected to the connections of the plug pins(see view 1, fig. 5).Attention: When the fastening screws(item 3, fig. 4) get lost, they will have to bereplaced by similar screws or to be ordereddirectly from the manufacturer.Assembly is made in inverse order, after thecable has been connected.The inlets are electrically connected as shownin fig. 6 to 8.Fig. 6: After unscrewing the two screws item 3,the plug insert item 2 is removed from theflange item 2.Fig. 7: Now the connecting leads item 4 can beconnected to the terminals of the plug insertitem 2 as described in point 6.2.Fig. 8: Finally, using the self-cutting screwsitem 3, the plug insert item 2 is screwed intothe flange, observing its proper position.The connectible min. and max. conductorcross-sections shall be observed(see technical data).All screws and/or nuts of the supply terminals,also of those remaining vacant, shall betightened down.The supply terminals are designed for theconnection of copper conductors. If multi- orfine-wire connecting cables are used, the wireends will have to be handled in acc. with theapplicable national and international rules(e.g. use of sleeves for strands).Befestigungspunkt BSteckdose 16 A 4-pol.Item 3Item 3L1NPEItem 2 Item1Item 3Item 2View 1 View 2Item 2 Item 3 Item 1Item 2 Item 1Item 4Item 2 Item 1Fig. 4Fig. 5Fig. 6Fig. 7Fig. 8B BB BPlug and socket system for industrial use 16 A,3-pole, 4-pole, 5-pole, GHG 521GB
