AREA CLASSIFICATION "Dust" __-^^^"^

Zone 21: area in which an .explosive atmosphere in the form of a cloud of combustible dust in air is likely to

occur occasionally in normal operation.

Marking Ex ta/tb/tc Da/Db/Dc II 1/2/3 D in accordance with IEC 60079-0; 60079-31 ^1 ^ W

Principle: ^^^^ • •

The enclosure is sealed so tight, that no combustible dust can enter. The surface temperature of the external

.enclosure is limited. „ / . '. • .

Important design parameters: /TT^SfexJc^i^

• Minimum degree of protection in accordance with IEC/EN 60529 > IP 6X
