4 Installation
The detectors described in this manual are safety instruments intended to be installed in explosive
atmospheres and have been designed in compliance with standards EN60079-0 and
EN60079-1, EN 60079-29-1, CEI 60079-0 and CEI 60079-1.
Intervention in some sites may be subject to restrictions that we invite you to follow
for your own safety and those of others.
4.1 Positioning
The detector must be positioned as close as possible to sources of potential leakages, considering
airflows (e.g. upper and lower ventilation). The height is determined by the density of gas to
detect.
A detector will not be placed in front of an air inlet which brings clean air
This height may be adjusted to consider the specific conditions which may interfere on the risk
level (gas density, ambient temperature….)
There are no limit positions of the detector however it is
recommended to position the detector vertically (ie with the
cartridge pointing downwards).
Air velocity limits: 6 m/s.
4.2 Assembly
Use the two 7 mm diameter holes and the half-slotted hole to secure the support.
It is highly recommended to install the support with cable-gland downward in order to avoid
water infiltrations. In case of horizontal position, it is advised to make one or two loops with the
cable at the entry of the cable-gland.
