housing:
1. Open the cable gland and the housing cover on the terminal head or the field
housing.
2. Feed the cables through the opening in the cable gland.
3. Connect the cables as shown in → 19. If the head transmitter is fitted with push-
in terminals, pay particular attention to the information in the "Connecting to push-in
