fall under DGRL and are in Kat I or higher. Fluid group 1 includes explosion-prone, inflammable and
poisonous matters. Die Fluid group 2 includes media, which are no included in fluid group 1.
Note concerning ex-guideline 94/9/EC (explosion guideline ATEX):
The product is not subject to guideline 94/9/EC, since due to the loads occurring during practical
operation, there is no effective source of ignition even in case of an error case to be assumed. This also
applies for spring-loaded components, in fluid-filled rooms. In case of electric drives, sensors or other
electric components the application as per 94/9/EC is to be checked separately.
