3.1 Installation of the DIN 175301-803A / C angled connector
Insert the screwdriver into the installation opening to pry the terminal block (2) out of the
housing (4).
Select a wire diameter appropriate for the cable entry in the housing. Slide the cable
through the cable gland (7), the ring (6), the seal (5) and the housing (4).
Connect the ends of the cable to the terminals in the terminal block (2) as shown in the
connection drawing.
Press the housing (4) onto the terminal block (2).
Screw the cable to the cable gland (7). Ensure that the seals are not damaged and that the
cable gland and seals fit properly to provide the proper IP protection.
Place the square gasket (1) over the connecting pins in the sensor housing.
Slide the terminal block (2) onto the connecting pins in the housing.
Use the locking screw (8) to fasten the assembled angled connector to the sensor.
3.2 Installation of the M12 mating connector
The M12 mating connector must be tightened to a torque of 0.6-1.5Nm to ensure that the required
leak-tightness category is provided.

Troubleshooting
DANGER
Do not open the connections unless they have been depressurized! The pressure sensor is
maintenance-free. Only have repair work performed by the manufacturer.
Never use any sharp, pointed or hard objects to clean the device, as this could damage the
sensitive membrane of the pressure fitting.
Take all necessary precautions for residual material in the pressure sensing devices that
have been removed. This residual material can be hazardous to humans, the environment
and the facilities!
If faults cannot be eliminated, de-activate the pressure sensor and secure it against
inadvertent/unauthorized re-activation.
