6.2 Application conditions
0.8 to 1.1 bar abs
-20°C to 60°C The EC type test is based on atmospheric conditions of 0.8 to 1.1 bar abs and
ambient or medium temperatures of -20°C to 60°C. If the pressure and temper-
ature levels differ, the operator needs to document the suitability in the explo-
sion protection document.
Ambient temperature -20 … +60 °C
Storage temperature -20 … +85 °C
Atmospheric conditions 0.8 … 1.1 bar abs
Max. allowed temperature of medium Depends on model and zone
Min. temperature of medium -20 °C
Specific minimum density of medium ρ = 0.6 kg/dm
3
Installation position horizontal
Type of protection: IP 65 acc. to DIN EN 60529
Zone 1 and 2
Max. allowed temperature of medium max. occurring surface temperature
The max. occurring surface temperature corresponds to the medium temperat-
ure. Temperature classes acc. to DIN EN 60079-14 and ignition temperatures
need to be taken into account for the respective application. In order to avoid
additional heating, the devices may not be exposed to additional direct sunlight
during operation.
Temperature class T1 T2 T3 T4 T5 T6
Max. surface temper-
ature 450 °C 300 °C 200 °C 135 °C 100 °C 85 °C
Zone 21 and 22
Max. allowed temperature of medium T80 °C
If the medium temperatures exceed 80 °C, the operator must examine the igni-
tion temperatures of the relevant dusts.
