You have to remove this plug before electrical connection.
NPT thread
In the case of instrument housings with self-sealing NPT threads, it
is not possible to have the cable entry screwed in at the factory. The
cable gland is therefore covered with a red dust protection cap as
transport protection.
Note:
To ensure the housing protection class, you must replace this protec-
tive cap with an approved NPT cable gland before setup.
Note:
Do not use grease when screwing in the NPT cable gland or a conduit
steel pipe.

3. Loosen compression nut of the cable gland and remove blind
plug
4. Remove approx. 10 cm (4 in) of the cable mantle, strip approx.
1 cm (0.4 in) of insulation from the ends of the individual wires
5. Insert the cable into the sensor through the cable entry
