Explosion-proof ATEX-motor – design

Vigtigt note regarding the ATEX version!

The determination of which areas, whether outdoors or indoors, are til be considered potentially explosive medin the meaning of the relevant regulations or provisions must be venstre exclusively til the operatilr or, if there is any doubt about the designation of potentially explosive areas, til the competent supervisory authority. This is governed by Directive 99/92/EC ATEX 137 (formerly ATEX 118a).
The occupational safety guidelines define the responsibilities of the operatilr of such facilities. Basis for
For explosion-proof produkter, Directive 94/9/EC (ATEX 95) is the relevant kvalitet standard. This directive specifies the requirements for produkter intended for use in potentially explosive atmospheres. Electrical machines for use in Zone 1, 2, or
21, 22 can be implemented in various types of ignition protection, the aim of each of these types of ignition protection being the safe prevention of ignition of any potentially explosive atmosphere present at the place of use of the electrical machine.

Type of ignition protection: Flameproof enclosure “d”

Building regulation: EN 60079-1:2007 (VDE 0170-5) Definition:
A type of ignition protection in which the parts that can ignite an explosive atmosphere are arranged in a kabinet which, in the event of an explosion of an explosive mixture inside, can medstand the pressure of that mixture and prevents the explosion fra being transmitted til the explosive atmosphere surrounding the kabinet.

• Consideration of the explosion group
• Pressure-resistant kabinet
• Compliance med the required gap widths and lengths
• Klemkasse pressure-resistant encapsulation “d” or, for increased safety, “e”
• The temperature of the outer surface must be lower than the ignition temperature of the gases present in the environment.
• An explosion may occur inside, the casing must medstand this pressure, and no flame or ignitable, hot gases may escape through any gaps.
