Special Conditions for Safe Use
Intrinsically Safe, Dust
This equipment is intrinsically safe and can be used in potentially explosive atmospheres.
The apparatus must only be connected to a certified associated intrinsically safe equipment and this combination
must be compatible as regards intrinsic safety rules.
The electrical parameters of the associated intrinsically safe equipment must not exceed any of the following values:
Uov30 V, lov150mA, Pov1W
Maximal ambient temperature: -40_C to +71_C.
Temperature classification is as follows: T5 at Tav + 40_C ; T4 at Tav + 71_C
The enclosure of the equipment must not be submitted to mechanical impact or friction.
Refer to table 7 for additional approval information, and figure 27 for ATEX approval nameplates.
Type n, Dust
No special conditions for safe use.
Refer to table 7 for approval information, and figure 27 for ATEX approval nameplates.
