13 DESCRIPTION OF COMPONENT

The V2081, 7092 & 8092 Series Instrument Enclosures & Junction Boxes, examples of which are detailed in Figures 1 to 3, are cylindrical single compartment enclosures comprising a base and threaded cover with a maximum internal volume of 610 cm³. The enclosures are manufactured from stainless steel or cast aluminium that may have an epoxy paint coating. The cover may be blind or contain a circular tempered glass window. Each enclosure may have a number of conduit openings and sizes as detailed in the Table 1.

The 8092WT product range may optionally comprise of a T079 base enclosure arrangement which utilises an existing 8092WT enclosure base having four additional blind M5 mounting holes located at the bottom entry and two M8 mounting holes. The T1 cable entry is located on a surface angled at 2 degrees on the existing enclosure base, whereas on the T079 base enclosure, the angle is not present, to allow entry devices fitted to sit perpendicular and enable conductive contact. The cover remains unchanged.

The enclosures meet the requirements of IP 66 Variation 1 - This variation introduced the following change: i. The recognition of the introduction of 1” NPT, M25 and M27 cable entries in the 8092 range of

enclosures, Table 1 was amended to reflect this. Variation 2 - This variation introduced the following change: i. Following appropriate re-assessment to demonstrate compliance with the requirements of later

standards, the following, previously listed documents, EN 60079-0:2006, EN 61241-0:2006 and EN 61241-1:2004, were replaced by those currently specified, the marking was amended accordingly.

Variation 3 - This variation introduced the following change: i. The addition of an alternative option within the 8092WT product range, which introduces the T079

base enclosure arrangement. Documents 8092-108-XX and 8092WT-XX T079 were introduced to reflect this modification, the product description being amended accordingly.

Variation 4 - This variation introduced the following changes: i. Following appropriate assessment to demonstrate compliance with the latest technical knowledge,

EN 0079-0:2012, EN 60079-1:2007 and EN 60079-31:2009 were replaced by EN 60079-0:2012+A11:2013, EN 60079-1:2014 and EN 60079-31:2014, the markings were updated accordingly to recognise the new standards, and a Schedule of Limitations was added.

* Denotes that an adhesive label is fitted detailing the threadform when a metric threadform is selected.

Model Nos. 7092WT, 7092WM, 7092AT & 7092AM are coated with epoxy paint. Model Nos. 7092CT, 7092CM, 7092NM & 7092NT are uncoated.








ii. Other external thread types (other than metric or NPT) are not permitted as an option for cable glands in field wiring installations in EN 60079-1:2014 Annex C.2.2, therefore a specific condition of use is added to this certificate.

Variations to such EC-Type Examination Certificates may continue to bear the original certificate number issued prior to 20 April 2016.)

• The introduction of Variation 4. 15 SCHEDULE OF LIMITATIONS 15.1 The window cement has an upper service temperature limit of +95°C. 15.2 The window has an upper service temperature limit of +85°C. 15.3 The contents of the V2081, 7092 & 8092 Series Instrument Enclosures & Junction Boxes may be placed

in any arrangement provided that an area of at least 40% of each cross-sectional area remains free to permit unimpeded gas flow and, therefore, unrestricted development of an explosion. Separate relief areas may be aggregated provided that at each area has a minimum dimension in any direction of 12.5 mm.

15.4 When this product is certified as Ex equipment, the label for the Ex component (external to the enclosure)

shall be removed, in accordance with EN 60079-1 Annex D.8. 15.5 External thread types other than metric or NPT are not permitted as an option for cable glands in field

wiring installations. Therefore, the user shall ensure that no such cable glands are installed in the enclosure entries.
