Thisis advisable because it means that only one bus cableneeds to be run (to RS 485 connection on the CU-S+control module) between the external modules and therelated controller (in the AT-S+ cabinet or its substations).The cables for the 24V supply for the bus modules can belaid with a 4-core cable together with the bus.The 24V supply and the bus cable can now be loopedthrough inside the sub-distribution board on the devices.In many cases it is desirable to all controlgear to beconcentrated in a single control cabinet (e. g. for thecentral operation and monitoring of all switching elementsand circuits). For such requirements CEAG can supply apreassembly for fitting DIN mounting rails in the cabinetAT-S+ to which external modules can then be mounted(accessory part no. 400 71 347 125). With this type ofassembly a cable must be run between the cabinet andthe distribution board for the mains supply (of the moni-tored circuits) for each command.You will find the block connection diagram and furthertechnical information on the page 26.The terminal assignment will be found on the device. Theterminals can accept cables up to 2.5mm² cross-section.Terminal assignment on the DLS/3Ph-bus-module(top/bottom) X = terminal not assignedTerminal assignment on the TLS bus module(top/bottom) X = terminal not assignedThe supply for the glow lamps in the light pushbuttonsis connected to the upper terminal strip on the module,terminals N (O) and L (U); the PE terminal is alsoconnected to the PE terminal of the SU or SOU!6.6.2 TLS-Bus-ModuleIf possible these modules should be installed direct inthe sub-distribution boards which supply the associatedcircuits (for the general lighting or stairwell lighting).They can be mounted in the AT-S+. Otherwise the samecriteria for selecting the installation position apply as forthe DLS/3Ph bus modules.You will find the block connection diagram and furthertechnical information on page 24!
