Explanation
Mark for preventing explosions
II Device group II: for potentially−explosive environ
ments except for mines and their surface installa
tions
3 Device category 3: for use in zone 2 and zone 22
G/D G/D range: for gases and dusts
E Constructed in accordance with European standard
Ex Explosion−protected operating medium
n Ignition protection type n
In normal operation, the operating medium is not
able to ignite an ambient potentially−explosive
atmosphere up to the ascertained temperature
class (here T5).
Further condition: It must be used in zone 2
(improbable occurrence of a potentially−explosive
atmosphere of gas).
A Operationally electric non−sparking operating
medium
II Device group II, see above
T5 Temperature class T5, i.e. the maximum surface
temperature in respect of gases, fumes or mist is
100 °C
X Special condition for installation and use, here:
plugs and adapters of the electric connections must
comply at least with protection class IP64
Limits of the permitted ambient temperatures
Maximum surface temperatures in respect of the ignition
of dusts, fibres and fluff
