Components for process control or electrical installation that are not specifically designed for hazardous areas can be installed in the flameproof Ex d enclosure. In addition to isolated barriers from Pepperl+Fuchs, these components may include DCS and ESD systems or other devices according to the respective customer specification. The flameproof enclosure ensures that the non-Ex devices do not pose a threat to the environment. Under ideal conditions, the Ex d enclosure is opened as little as possible after initial installation as special rules under IEC 60079-14 must be observed for opening and closing. The Ex e enclosure contains only accordingly Ex-certified components. This makes it much easier and safer to access than the Ex d section. Terminals and control elements can be serviced or replaced at any time, subject to compliance with the relevant regulations.
