Connection with cable extension
To lengthen the sensor connection beyond the length of the fixed cable, you require a junction box VS.
Always connect the sensor cable with the SXP plug to the junction box.
The cable extension to the transmitter then depends from the transmitter version, i.e. field device or panel
mounted device.
