INTRODUCTION
ATEX unit Selection
Since the selection of gear units for hazardous locations requiring ATEX certifi cation can be somewhat
confusing, NORD has simplifi ed the process.

2. Contact NORD to request the ATEX inquiry form. The form is also available at www.nord.com.
3. Fill in the ATEX inquiry form
• Select the hazard, Gas or Dust
• Select the zone
• Select the temperature class (for gas) or select electrically conductive or non-conductive for dust hazards
4. Return the completed ATEX inquiry form
5. NORD engineers will review your selection to ensure it conforms to ATEX guidelines
6. If you selection is approved, Customer Service will quote the unit. If not, NORD engineers will make a unit
selection
recommendation.
ATEX Documentation
ATEX applications require more documentation than gear drive equipment used in non-hazardous locations.
Each ATEX certifi ed NORD gear drive undergoes verifi cation to ensure it will safely operate within the limits
of the ATEX specifi cation. NORD stores and supply this document to the customer upon request. In addition,
ATEX specifi c operation & maintenance instructions are included with each equipment delivery in the lan-
guage of the equipment builder and end user.
