24/7 ASSET MONITORING SOLUTION UM00014EN-AF DIN RAIL MOUNTING CAUTION ENSURE THAT THE LOW-LEVEL COMPARTMENT WHERE THE READER IS MOUNTED IS SUFFICIENTLY VENTILATED TO PREVENT OVERHEATING. THE DEVICE MUST BE ELECTRICALLY GROUNDED FOR EMC COMPLIANCE. The reader is designed for installation on a grounded 35 mm DIN rail. DIN rail fixation is integrated on its rear enclosure. -
Page 17: Reader Emplacement
24/7 ASSET MONITORING SOLUTION UM00014EN-AF 1.7.1 READER EMPLACEMENT The reader is intended to be installed in the low voltage compartment of the switchgear. The other electrical assets are recommended to be weather protected in an enclosed location. Figure 11: Reader emplacement in switchgear The reader is required to be installed within a maximum distance of 10 meters from the antennas, corresponding to the maximum length of the antenna coaxial cable for SAW temperature sensors and partial discharge measurement. -
Page 18: Wiring
24/7 ASSET MONITORING SOLUTION UM00014EN-AF WIRING POWER The reader power connector is a 2-pin male connector. This screw connector supports from 16 to 26 AWG wires. For stranded conductor use connector ferrules on the termination. Figure 13: Connector ferrule 1.8.1 INPUT POWER The reader operates at 24VDC nominal with a total power consumption of 6 Watts maximum. -

Page 20: Communication Connections
24/7 ASSET MONITORING SOLUTION UM00014EN-AF COMMUNICATION CONNECTIONS The components are used to connect Modbus devices, energy communication systems and industrial equipment with each other and to SCADA or cloud systems. The reader could be connected to a network using RS485 Modbus-RTU or Ethernet Modbus-TCP. 1.9.1 CABLING FOR RS485 COMMUNICATION SENSeOR recommends the use of shielded cable for the RS485 wiring, providing at least one twisted pair, one single line, and a drain wire. -
Page 21: Bus Data Rate
24/7 ASSET MONITORING SOLUTION UM00014EN-AF 1.9.3 BUS DATA RATE The RS485 bus data rate is dependent on the bus cable length and the number of readers on the bus. In industrial environments, slower data communication rates are generally more reliable. 1.9.4 BUS LENGTH Bus cable length has an impact on the overall data rates that can be achieved. -
Page 22: Cabling For Ethernet Communication
24/7 ASSET MONITORING SOLUTION UM00014EN-AF 1.9.7 CABLING FOR ETHERNET COMMUNICATION SENSeOR recommends the use of shielded Cat 5e SFTP cable for the Ethernet wiring. Readers Ethernet network is provided by a fixed configuration more detailed below. The IP address is defined by the last four digits of the product serial number printed on the side of the reader. -
