Mounting position.
Detectors of the ASG-2000 series are recommended to be installed in a vertical position with the gas
inlet down, this position guarantees the best protection against dust and splashes of water. In the case
of methane detectors, due to the mounting height, a horizontal position (increased susceptibility to
dust accumulation in the gas inlet element) or ceiling mounting is possible although not recommended.
Installation with the gas inlet directed upwards is not allowed, in this position the detector is exposed
to water ingress and excessive accumulation of dust in the gas inlet. Mounting positions are shown in
Figure 2.
For propane-butane detectors, due to the low mounting height in places exposed to mechanical
damage, it is recommended to use a suitable cover.

Detector installation.
!!! PLEASE NOTE
All work related to the installation of detectors should be carried out with the
disconnected power supply.
Before mounting, check the validity of the calibration certificate.
Remove the detector cover and the sensor module to protect it from dust. Mount the detector to the
ground with 4 wall plugs.
Terminal block connectors allow the use of multiple wire cables like wire and cord with a cross section
between 0.25 and 2.5 mm
2
. The diameter of the cable is limited by the cable glands used and amounts
to 5 ÷ 10
mm. The cable ends must be insulated to a length of 8 mm.
