ATEX is the conventional name of the Directive 2014/34 EU for the equipment intended for use in potentially explosive atmospheres.
Motive Variable Frequency Drives NANO Ex and NEO-Ex differ from standard NANO and NEO because they are designed to be used, like motive "Ex" gearboxes, in the ATEX zones 21 and 22, Categories 2 and 3, Groups A, B and C, Dust
| Cat | Zone | Description | motive "EX" |
| 1 | 20 | A place in which an explosive atmosphere in the form of a cloud of combustible dust in air is present continuously, or for long periods or frequently | |
| 2 | 21 | A place in which an explosive atmosphere in the form of a cloud of combustible dust in air is likely to occur in normal operation occasionally. | yes |
| 3 | 22 | A place in which an 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 persist for a short period only. | yes |
NANO Ex and NEO-Ex are in fact certified for such zones according to the norms IEC 60079-0:2011 - EN 60079-31:2014 by a notified body
