Depending on the type of installation, a suitable cable in accordance with Type A oder B of IEC 60079-14, must be used. ATEX 2G Specific conditions Lead insertion The connection cables should either be fixed when laid and mechanically protected or installed in such a way, that a force of 30 N applied in the direction of the cable inlet for one hour, does not lead to any visible displacement of the cable connections, even though the cable sheathing is displaced, see also IEC 60079-11. Depending on the type of installation, a suitable cable in accordance with Type A oder B of IEC 60079-14, must be used.
