8. Commissioning
Assembly 8.1.
1. Take the VOC sensor from the box and remove the packaging.
2. Drill holes to mount the sensor, observing the position of the cable outlet (Fig. 1).
3. Insert the 5 mm wall plugs included in delivery into the bore holes.
4. Screw in the screws until the screw heads are 5 mm from the wall.
5. Open the sensor.
6. Feed the connection wires through the wire outlet prior to mounting.
7. Place the housing on the screws so that the LEDs are arranged on the right, then turn the housing so that it is straight.
8. Using a small Phillips screwdriver, connect the power supply, along with any relay output and the voltage signal output(s). See pin
assignment, figure 2. The connection wires can be fed out from the housing directly beneath the compression fittings.
Avoid static charges and contact with electrical contacts. Electrostatic discharges can damage the device or sensor! Ensure that
no electrical voltage is applied on the wires. Connect the power supply (14 - 27 V DC) to the screw terminal AN1. See pin
assignment, figure 2.
9. Carefully insert the cover onto the enclosure base, so that the ventilation slots face upward and downward and the LEDs are
visible on the right-hand side.
