Connection of the sensors and power supply

Important:
  • All wiring work must be performed in the de-energised state.
  • Ensure installation is completed correctly.
  • Comply with existing legal and/or operational directives.
  • Improper handling can cause injuries and/or damage to the instruments.
  • Run all data and power cables so that they do not pose a trip hazard and ensure that cables do not have any sharp bends.
  • Current and data cables must not exceed a lenght of 30 m.
  • The myDatalogEASY IoT ATEX must not be operated in the field with the cover open.
  • The myDatalogEASY IoT ATEX cannot be operated without a power supply unit.

Note: The first two steps are only necessary if the device is already in operation and the wiring needs to be modified.
  1. Remove the four screws that secure the housing cover. Now open the myDatalogEASY IoT ATEX .
    Important: In the event of adverse weather conditions including rain or in a location where water can penetrate from above, suitable measures must be implemented to protect the device from penetrating moisture when the housing cover is open.
  2. Remove the power supply unit from the myDatalogEASY IoT ATEX . Use the strap provided to remove the power supply unit.
  3. Connect the ground connection of the myDatalogEASY IoT ATEX to the ground potential of the system.
  4. Connect your sensors to the sensor connectors. If your sensor does not have a compatible connector, you can use the Connection cable 7-pins for sensors 2,8 m (206.602).
    Important: If you operate the myDatalogEASY IoT ATEX in areas with a zone 2 explosive atmosphere, observe the ATEX requirements when connecting the open ends of the Connection cable 7-pins for sensors 2,8 m (206.602) with your sensors (e.g. distances between the signal lines).
    Important: If you use the Connection cable 7-pins for sensors 2,8 m (206.602), the joint between the sensor cable and sensor must be suitably protected against the penetration of moisture and dust. You can use the Clamping tube(300256) or Pressure compensation tube (300131) for this purpose (see Use of the clamping tubes).
  5. If you would like to use an external supply or charging voltage, you should connect the corresponding cable with the supply or charging voltage connection in the de-energised state. Use the Connection cable 2-pins for supply 5m (301192) to connect your power source to the connection for the supply or charging voltage. Further accessories are detailed in the chapter Spare parts and accessories.
    Important: The connection point between the "Connection cable 2-pins for supply 5m " (301192) and the power source must always be outside the area with a zone 2 explosive atmosphere.
    Important: Use suitable means to protect the connection point between the "Connection cable 2-pins for supply 5m " (301192) and power source against the penetration of moisture and dust. You can use the Clamping tube(300256) for this purpose.
  6. Affix corresponding protective caps to all of the connectors that are not required.
    Important: All unused connectors of the myDatalogEASY IoT ATEX must be sealed watertightly using the protective caps supplied. Otherwise the degree of protection for the entire device is not guaranteed and the manufacturer's warranty is void.
  7. Connect the antenna (see Connecting the mobile network antennas). The antenna is not included in the scope of delivery and must be ordered separately.
  8. Insert the power supply unit.
    9. The following step is not mandatory.
  9. Check whether the connection to the myDatanet has worked correctly (see Testing communication with the device).
  10. Close the housing cover. The best option is to tighten the four screws crosswise (torque: max. 1 Nm) so that the housing cover is positioned evenly.
    Important: Ensure that the seals are clean and intact before closing the housing cover. Remove any impurities and/or dirt. The manufacturer shall not be liable for any damage to the device caused by leaky or faulty seals.

  11. Check that the housing cover is positioned correctly on all sides and that no foreign materials have been trapped between the housing and housing cover.
    Important: The manufacturer is not liable for any damage that is caused by housing covers that are not closed correctly.

    12. The following step is only necessary if you are using an external supply or charging voltage.
  12. Now switch on the external supply or charging voltage.
    Tip: If you are using a power supply unit without an integrated energy store, the external supply or charging voltage must be switched on before the optional step during which the connection to the server is tested.
