The Canadian Standards Association has issued a component certification for the
VQ500 Series as an Explosion Proof Enclosure for use in Class I hazardous locations. It
has satisfied the requirements of CSA standard C22.2 No. 30-
2589677. The Canadian Standards Association has also assessed the VQ500 Series to
th
Underwriters Laboratories Inc. recognise the VQ500 Series as a component for use in
intrinsically safe apparatus
in Class 1, Division 1, Groups A, B, C and D hazardous
locations. It has satisfied the requirements of UL 913, 7th edition. File E186043.
INSTRUCTIONS SPECIFIC TO HAZARDOUS AREA INSTALLATIONS
(Ref. EU ATEX Directive 2014/34/EU)
1. The VQ500 Series Gas Sensing Heads are component approved only and may not be used as standalone items in a hazardous area
without further protection.
2. The VQ500 Series Sensing head shall be used in conjunction with apparatus providing an intrinsically safe supply having a maximum output
(P
o
) not greater than 2.5 W.
3. For the purpose of temperature classification of the apparatus in which the VQ500 Series Gas Sensing Head is used, the maximum
temperature rise on any external surface does not exceed 64 °C.
4. When the VQ500 Series component is utilized in equipment that is intended to be used in Group I applications, it shall be suitably protected
to ensure that it will withstand an impact energy in excess of 7 J low risk of impact value specified in EN 60079-0 clause 26.4.
5. The VQ500 Series Gas Sensing Heads have not been assessed as a safety device (EHSR 1.5).
6. There are no user-serviceable parts in the component.
7. The end-user/installer shall be aware that the certification of the VQ500 Series Gas Sensing Heads relies on the following materials used in
its construction, which are suitable for most common applications:
Enclosure .............................................Stainless steel
Mesh ....................................................Stainless steel
Bushing ................................................Epoxy resin
In accordance with the Note in EN60079-0:2006 clause 6.1(a), the end-user/installer shall inform the manufacturer of any adverse
conditions that the VQ500 Series Gas Sensing Heads may encounter. This is to ensure that the VQ500 Series Gas Sensing Heads are not
subjected to conditions that may cause degradation of these materials.
8. The VQ500 Series Gas Sensing Head shall only be used in an ambient temperature range of −40°C and +55°C.
