Use the delivered cable LEONI L45551-P42-B5 and confection the cable as explained in the user manual
²
of the LPIT GIS sensor.
The L45551-P42-B5 cable has 4 twisted pairs: 1 pair for the low-power voltages, 1 pair for the low-power
currents, and 2 pairs for the PT100 temperature sensor connection.
Connect the signal cables to the corresponding terminals, refer to
