How is the AC004 to be installed?

There are two installation options

The AC004 device can be adjusted for either flat surfaces or round profiles by means of the corresponding installation adapters.


Installation on a flat surface

The sensor is inserted into the installation adapter bottom section first. The sockets of the installation adapter must engage with the lower recesses of the sensor. Press the lower section of the sensor and click it fully into the adapter. The sensor engages with an audible click. Then fix the sensor to the surface using 6 screws.

Installation on a round profile

Place the installation adapter on the sensor. Now thread two fixing straps for clean-line cylinders through the eyes of the installation adapter and fix it to a round profile together with the sensor.
