ATEX-proof electromagnet
For use in hazardous zones 2 and 22 exclusively
Characteristics
- For zones 2 (gas) or 22 (dust), areas in which there is either no hazardous atmosphere at all during normal operation or only for a short period
- Three features distinguish it from the normal EM GD 70 R39I:
- Connection terminal for the prescribed equipotential bonding
- Larger base plate
- Special label for hazardous areas
- Equipped by default with diodes to suppress the induced current on opening (spark extinction diodes) and polarity protection
- As counter piece for the electromagnet a counter plate needs to be fixed
- Some articles may differ from the photo

Installation
Installation notes
Installation notice
- The explosion-proof magnet is mounted directly on the wall behind the door that needs to be kept open.
- Important: The explosion-proof EM GD 70 R39I Ex2 DICTATOR electromagnet can be used exclusively in zones 2 and 22!
- To protect the ex-proof magnet from a possible short circuit, a fuse, max. 3 x IB according to IEC 60127-2-1, corresponding to the rated current of the magnet has to be connected upstream to the magnet (G fuse 200 mA type M). A terminal is provided on the mounting plate for the connection of the equipotential bonding with a minimum cross section of 4 mm².
- A Hirschmann connector is provided for the electrical connection of the magnet. The connection polarity in the connector is as follows: screw terminal 1 = (+), screw terminal 2 = (-). After connecting the magnet, it has to be made sure that the casing of the connector is again safely and completely closed.
- It is essential to protect the magnet against mechanical impacts. Furthermore all regulations for hazardous areas have to be followed.
- You can find more installation information under ‘Downloads’.
Fuse / Fuse Carrier for Explosion-Proof Magnets
The fuse carrier with the prescribed fuse is placed directly into the feeding line to the ex-proof magnet. There are available two different types of fuse carriers:
- Fuse carrier for solding directly into the feeding line, with bayonet catch. Dimensions of the fuse carrier: L = 43,2 mm, Ø 14,2 mm (suitable for cables with a cross section of max. 4 mm) (part no. 040587)
- Fuse carrier for mounting on top hat rails, with pivoting retaining bracket (part no. 040588)
Advice:
- According to fire protection regulations, a switch has to be installed next to the fire protection door for releasing the electromagnet (ex-proof hand switch, part no. 700232).
- If the switch is connected within the hazardous area, the connection cable has to be connected in a casing which corresponds to the demands of an acknowledged ignition protection type in accordance with EN 50014, section 1.2. During installation and connection, all relevant regulations for hazardous areas have to be observed.
