5 XN ECONTCTOR The range Technical information technology that prevents from all accidents The ECONTCTOR TM XN operation provides a high safety to the users. To release the plug, simply press the latch and pull the plug simultaneously (pictures 1 & 2), which breaks the circuit. Then, twist anticlockwise and withdraw the plug (picture 3). This operation is totally safe because the circuit is open. When the plug and socket-outlet are separated, active parts are protected against the ingress of finger or from wires exceeding 1 mm diameter, thanks to the socket-outlet safety shutter (IP4X protection with open lid) Compliance with the TEX directive The ECONTCTOR XN range complies with the new TEX directive dated 23 rd March 1994 and 199/92/CE.

They are category 2, i.e. they can be installed in zone 1 gas (and therefore 2) and zone 21 dust (and therefore 22). Reminder: Zone 0 (20): the atmosphere is always explosive Zone 1 (21): the atmosphere is occasionally explosive Zone 2 (22): the atmosphere is accidentally explosive 3. Our products are intended to be installed in explosive gas ( G ) or dust ( ) atmospheres. 4. In zone 21 (dust), the maximum product temperature is 85 C for ambient temperature of 40 C: their temperature class is therefore T6. 5. The protection modes of our products are e (increased safety: terminals, enclosures ) and d (explosion proof gaskets for arc chambers), IIC means that our products can be installed in all types of gas including the most hazardous ( C gases subdivision including hydrogen). 6.
