User Guide
Be used with gases in groups:
Group A propane
Group B ethylene
Group C hydrogen
In gases which may be safely used with equipment having
a temperature classication of:
T1 450°C
T2 300°C
T3 200°C
T4 135°C
In ambient temperature of between
-20°C and +60°C.
This allows both types of panel lamp to be installed in all
Zones and to be used with most common industrial gases.
3.1.2 Dust atmospheres - option should be specied at
time of ordering.
The BA390X and BA390XS panel lamps have been
certied:
Group II Category 1D
Ex ia IIIC T135°C Da
–20°C ≤ Ta ≤ 60°C
When connected to a suitable system the lamps may be
installed in:
Zone 20 explosive atmosphere in the form
of a cloud of combustible dust in
air is continuously present, or for
long periods or frequently.
Zone 21 explosive atmosphere in the form
of a cloud of combustible dust in
air is likely to occur occasionally in
normal operation.
Zone 22 explosive atmosphere in the form
of a cloud of combustible dust in
air is not likely to occur in normal
operation, but if it does occur, will
only persist for a short period.
Be used with dusts in subdivisions:
IIIA combustible yings
IIIB non-conductive dust
IIIC conductive dust
Having a minimum ignition temperature of:
Dust cloud 202°C
Dust layer on 210°C
lamp up to
5mm thick.
Dust layer on Refer to IEC 60079-14
lamp over
5mm thick.
At an ambient temperatures between:
-20°C and +60°C.
3.1.3 Input safety parameters
The IECEx and ATEX input safety parameters Ui and Ii for
the BA390X and BA390XS lamps are the same, but the
input power Pi are different for gas and dust atmospheres.
Gas atmosphere:
Ui = 30V
Ii = 159mA
Pi = 1.2W
Ci = 0
Li = 0
Dust atmosphere:
Ui = 30V
Ii = 159mA
Pi = 0.683W
Ci = 0
Li = 0
BA390X and BA390XS panel lamps may be powered
from any intrinsically safe voltage source with output
parameters Uo, Io and Po equal to, or less than these
lamp input parameters.
