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 pro-
tective 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.
Maximum torque see chapter " Technical data".
We recommend to connect the cable screening to ground potential
at one end on the supply side when using shielded cable.
Metric threads
In the case of instrument housings with metric thread, the cable
gland is screwed in at the factory. It is sealed with plastic plugs as
transport protection.
