Figure 9: Correct mounting of the gas detector
The manufacturer recommends application of the Mounting Bracket WM8 (see Table 13) – since it enables
easy calibration of gas detectors and protects their housings against damage.
First the mounting bracket should be mounted to a support structure (wall) by means of two rawlplugs or
M6 bolts.
Then the detector can be fixed to the bracket by means of two M6 bolts included into the device package.
5.2.3 Electric network
The applied flameproof cable glands allows to introduce cables with diameters of a specific range. The
suggested cable types are included in the table in appendices [6],[7], [8] and [9].
When performing electrical connections, it is necessary to observe the following order:
make sure that the connected cables are disconnected from any electrical circuits and potentials,
make sure that during installation there is no risk of explosion or fire,
unscrew and remove the cover of the detector,
untighten the cable gland,
after preparation (see appendix [9]) thread the cable through the gland – For more details please
refer to the manual POD-066-ENG „Cable glands used in offered devices”.
Make sure that the cable outer diameter corresponds to the type of cable gland.
properly lay the cable so that it is not influenced by mechanical stress and the possibility of getting
into the water sensor flowing down the wrongly laid duct,
tighten the cable gland,
tighten the detector cover, making sure that the seal is in place,
