The enclosure protection of the intrinsically safe enclosures ?i? is based on the low voltage connections in the enclosure, e.g. data or telephone lines. Thanks to external earthing and the very small amount of ignition energy and temperature rise, the Ex-i junction boxes can be assembled with the maximum amount of terminals, without any complications. By the exterior earthing, the enclosures are included in the potential compensation. This completely avoids electrostatic charging and sparks resulting from it.

The enclosure should also be fitted with visually identifiable intrinsically safe blue cable glands and terminals in order to give notification to the installer that intrinsically safe power circuitry is fitted within.
