Connect Input Wires

To ensure a clean stable reading, keep field wiring as short as possible to maintain signal integrity and use shielded twisted pair wire such as Alpha 2463C.

Complete the following steps to connect input wires to the RM4013 or RM4016.

  1. If the input device has a voltage output, turn the device OFF to remove power from field wiring.

    If wires are to be buried or covered, conduit must be used to protect the wires.

  2. Using the following information, route input wiring through the fitting on the bottom of the enclosure (refer to Mounting Requirements for location of fitting) and connect to input channels:

    • CH1, CH3, CH4: analog (±5VDC)

    • CH2: analog (±100VDC)

    • CH5 Digital In: digital or accumulator

    • CH6 Digital In: digital

  3. Using bare copper wire, connect a ground wire to the ground lug on the bottom of the antenna with surge arrester. Ensure the other end of the ground wire connects to an earth grounding point.

  4. Connect input wiring from the unit to the output terminals of your device.

  5. Dress input wires inside the unit enclosure. To prevent damage to wiring, make sure input wires do not slip through the faceplate opening.

  6. Connect ground wire to the ground lug on the antenna with surge arrester (refer to RM4013 and RM4016 Unit Overview for location of ground screw).

  7. Tighten the fitting on the bottom of the unit enclosure.

  8. Turn ON the input device to restore power to field wiring.

  9. Turn ON the unit power switch (refer to Mounting Requirements for location of switch).

  10. Configure the unit for service using the information in Configuration Overview.
