2.4.1 Cable Termination and Hirschmann Models
All 206 models with a cable termination or Hirschmann connector vent through the cable to
maintain proper accuracy. Connection to the unit should be made in a junction box that is vented
to atmosphere, with care taken to ensure that the end of the cable is not blocked or sealed.
The following junction box configuration is a recommended method for connecting to 206 units
in order to achieve a moisture resistant and vented connection.
