18 en | Installation of a MIC440 Camera
Installation of the PSU within a hazardous area must have the standard PSU enclosure placed
inside an appropriate certified enclosure and four (4) Exd conduit glands (NOT supplied). The
power supply PCB is usually re-housed, by a third party company, within an Exd enclosure
which is then factory certified and shipped to site. Follow all manufacturers' instructions when
installing a third party Exd enclosure.
The figure below illustrates a typical installation of both a MIC440 and a MIC PSU in a
hazardous area. Note that the PSU is installed inside an enclosure that is certified for use in
hazardous areas.
