641MRS750881-MUMRemote Monitoring and Control UnitTechnical Reference ManualREC 5237.2. Terminal connectionsAll external circuits are connected to the terminal blocks on the rear panel. Terminalblock X1.1 for the measuring transformers consists of fixed screw terminalsfastened to the energizing input module. Each terminal is dimensioned for one max.6 mm2 or two max. 2.5 mm2 wires.ABB sensors (Rogowski coil or voltage divider) are connected to the connectorsX2.1...X2.9. A special type of shielded twin BNC connector (for example type AMP332225 or Amphenol 31-224) is used to improve reliability and protection againstdisturbances. The current sensor and/or voltage divider used must have a connectorElectromagneticemission testsEN 55011IEC 60255-25conducted RF emission (mains terminal) EN 55011, class AIEC 60255-25radiated RF emission EN 55011, class AIEC 60255-25CE approvalEN 50263Complies with the EMC directive 89/336/EEC and the LV directive 73/23/EECTable 7.1.-12 Data communicationFront interface,connector X5.3RS485 connectionLON bus or SPA bus, selectablethe fibre-optic interface module RER 103 is needed for galvanic isolationdata transfer rates SPA bus: 4.8/9.6 kbpsLON bus: 78.0 kbps/1.25 MbpsCommunicationinterface, connector X5.1remote communication protocolCommunicationinterface, connector X5.2parametrization, SPACommunicationprotocolsRefer to Section 9.2.
