potential sources of ignition and so falls
under the European Directive “Equip-
ment for potentially explosive atmos-
pheres” 2014/34/EU (formerly
94/9/EC).
The unit has a pressure-resistant en-
closure, i.e. a flameproof enclosure “d”
according to EN 60079-1.
The unit is classified as Group II, Zone
1, and so falls into Category 2 for gas
areas.
The unit is marked as follows:
The type approval procedure to di-
rective 94/9/EC or 2014/34/EU was
carried out by Bureau Veritas (No.
2004) as the notified body. The design
concept, manufacture, quality assur-
ance and the unit itself were subjected
to the specified examinations. There is
a copy of the “EU Type approval exami-
nation certificate”
EPS 15 ATEX 1 05 X
in the appendix to these instructions.
After 8000 switching cycles, the unit
must be checked by the manufacturer.
Failure to do so invalidates the explo-
sion proof approval.
