    Safety Guidelines for Hazardous Locations The TRC-8543 is suitable for use in hazardous locations; , and hazardous locations; and nonhazardous locations only. Follow these guidelines if you are installing the TRC-8543 in a potentially explosive environment. Not following these guidelines may result in serious injury or death.
  • Page 4 Internationally The TRC-8543 has been evaluated as equipment under DEMKO ATEX and is IECEx certified. Each TRC-8543 is marked and is suitable for use in Zone 2 hazardous locations, in ambient temperatures of -40 °C ≤ Ta ≤ 70 °C.

  • Page 5: Electromagnetic Compatibility Guidelines

    TRC-8543 Caution The system shall be mounted in an ATEX/IECEx-certified enclosure with a minimum ingress protection rating of at least IP54 as defined in IEC/EN 60079-15. Caution The enclosure must have a door or cover accessible only by the use of a tool.

    (6.0 in.) from the chassis and do not mount more than six cables directly beneath the chassis. You can route and strain relieve the TRC-8543 similarly to ordinary cables. You also can panel mount it using its removable jackscrews, zip tie, or screw mount it. The screw mounting holes support #6 and M3 screws spaced 35.56 mm (1.400 in.)

  • Page 7: Wiring To The Trc-8543

    Figure 4. TRC-8543 Connections The TRC-8543 has one 9-pin male D-Sub connector that provides connections to a CAN bus. The TRC-8543 has pins for CAN_H and CAN_L, to which you connect the CAN bus signals. Connect these signals using twisted-pair cable.
  • Page 8 When tightening the D-Sub connector jackscrews, do not exceed the maximum jackscrew torque of 0.56 N · m (5.0 lb · in.). The TRC-8543 receives power from the NI-XNET host port, but also requires an external power supply of +9 V to +30 V to operate in Low-Speed/Fault-Tolerant mode.

  • Page 9: Can Bus Topology And Termination

    TRC-8543 Connector Signal Name CAN Bus Topology and Termination A CAN bus consists of two or more CAN nodes cabled together. The CAN_H and CAN_L pins of each node are connected to the main CAN bus cable through a short connection known as a “stub.”...
