Pressure transmitters must only be connected by properly qualified personnel!
4.1 Assembly of the terminal box
Terminal box to DIN 43 650, Form A with Pg9 cable gland. Conductor cross-section up to
1.5 mm2 max., external dia. of conductor Ø 4.5 — 7 mm, Protection IP65.
Terminal box to DIN 43 650, Form C with Pg7 cable gland. Conductor cross-section up to 0.75
mm2 max., external dia. of conductor Ø 3.5 — 6 mm, Protection IP65.
The protection specified will only be achieved when the connector is firmly in position with the
corresponding seal.
to open up the connector:
Unscrew the screw (1).
Using a small, flat screwdriver, lever the inner part (3) out of the outer part (2) (see marking on the inner
part).
The inner part can be re-assembled and inserted into the outer part in 4 positions 90× apart.
4.2 Installing the attached connecting cable
(Extra code /73)
Minimum bending radius 120 mm (fixed cable run).
The cable must not be compressed. The end of the cable must be located in a dry room to
avoid condensation. It is best to route the cable directly into a switch cabinet.
When lengthening the cable, ensure that pressure equilibration is provided while avoiding the
ingress of moisture.
