12The feeder terminal includes two serial commu-nication ports, one on the front panel and theother on the rear panel.The 9-pole RS 232 connection on the frontpanel is intended for the connection of a PC tobe used for setting the CB/disconnector con-figuration, feeder oriented interlocking and otherparameters of the control module with a PC.The 9-pole RS 485 connection on the rear panelis used to connect the feeder terminal to the SPAbus via an interface module type SPA-ZC17_ orSPA-ZC21_.For its operation the feeder terminal requires asecured auxiliary voltage supply. The feederterminal’s internal power supply module SPGU240A1 or SPGU 48B2 forms the voltages re-quired by the measuring relay modules, thecontrol module and the input / output modules.The power supply module is a transformer con-nected, i.e. galvanically isolated primary andsecondary side, flyback-type DC/DC converter.The primary side of the power supply module isprotected with a fuse, F1, located on the PCB ofthe module. The fuse size is 1 A (slow).A green LED indicator Uaux on the front panel islit when the power supply module is in operation.There are two versions of power supply modulesavailable. The secondary sides of the modules areidentical, but the input voltage range is different.The input voltage range is marked on the frontpanel of the control module.SerialcommunicationAuxiliary powersupplyThe feeder terminal SPAC 536 C is designed forflush mounting in a 19" instrument frame. Theunit is fastened with four screws. The mountingdepth can be reduced by using a 40 mm raisingframe type SPA-ZX 19.When the feeder terminal is door-mounted, thedoor structure should be reinforced.Mounting anddimensiondrawingsSPAC 536 C2664 x ø8448 ±1465 ±0,519" (482,6)4657,5132,557,1133±157,1±0,5Panel cut-outFig. 5.
