Pay attention to the following points regarding electrical connections via cable gland:
The display can be dismounted as described in Chapter 3.2. Use a small screwdriv-
er to press the spring of the terminal block completely downwards before inserting
the cable. Otherwise, it is not possible to ensure a safe electrical connection.

tion to the case.
Turning the case in relation to the process connection (±170°) allows to choose the posi-
