An outgoingdistributor (part no. 400 71 347 160) can be used for threesinlge-phase supplies or one three-phase supply.Connecting the cables for the mains supply to a AT-S+ S..substation:• Ensure that the system and feeders are isolated andlocked out!• Run the feeders to/in the AT-S+ C.. control cabinet andin its routing system and to/in the control cabinet of theAT-S+ S.. (pos. 8).• Connect the earth conductor (PE-conductor) to theterminal block (pos. 5)• Connect the neutral conductor to the terminal block(pos. 4)• Connect the L conductors to the terminals on the outgo-ing feeder (pos. 2)The mains supply is connected in the control cabinet asdescribed in section 6.4.1.NOTESTo assist operations, outgoing distributors can be pulledforward off the busbar when the lock on the upper enclo-sure wall is released. Once the outgoing circuits havebeen connected, the outgoing distributor can be pushedback in position on the busbar with slight pressure andlocked in place.6.5 Connection and installation ofinternal modulesControl unit, DC/DC converter and AC supply are pluggedonto a module support. The circuit assemblies areinstalled on DIN rails.For simple installation/disassembly, connections with thesupport modules are via pluggable screw terminal blocksthat can be plugged onto or removed from the fronts ofthe modules.Fixed terminals are used with circuit modules due to thecurrent load of the connection terminals. Connectioncables of the terminals are applied to the terminal strip inthe upper area of the switching cabinet. Assignment is vianumber codes on the module and on the terminal block.The connection of external inlet and outlet lines is viathis terminal block row in the upper area of the switchingcabinet.NOTES• The circuit numbers used in the displays of the AT-S+controller and the displayed switch outputs of themodules are assigned by the choice of slots on thesubracks.• To ensure that replaced modules function correctlyunder the controller they must first be identified,activated and their parameters set up with controllersoftware.ATTENTION!Never fit or remove SU S+ modules in the Oncondition! Deactivate a SU S+ module at the CU-S+controller before removing or re-fitting it, e g fortesting For dismantling or modification work thecontroller must be disabledField 3 assembled with six modules SU S+Pos 1: D02 fuse holder for field 3Pos. 2: Terminals of field 1 modules.Pos. 3: Terminals safety source feed.Pos 4: Bus connection and 24V supply terminals.Pos. 5: Dip-switch for Bus termination resistance.143256.6 Connection and installation of externalSU S+ modulesEach CU S+ controller is able to operate with max.40 SU S+ and max. 25 DLS Bus modules via RS 485 Bus.In state of external installation please note the followingpoints.NOTES• The bus cables A/B and their screening must also beconnected to the system´s terminals. Please attendto the information regarding bus-technology andscreening!• Install/ activate the required terminating resistancewith the last device on a bus line (dip switch Pos 5 withSU S+ modules and bridging of terminal B1-B2 with DLSbus modules).• See chapter 8.4.5 „Operation of circuit set-up“ forregistering of external SU S+ modules. With DLS busmodules, set the address intended for the module, butavoid multiple assignment as this may cause operationalmalfunctions.• For further information please refer to the technicaldocumentation of the module!
