The printer doesn’t need to be switched off during this procedure. A window in the frontdoor and the additional lamp installed inside make it easy to read the printed labels. The enclosure also has a door on the side. The printer is installed on a sliding system, which makes it easy to carry out inspections and to apply new labels.
The Ex p systems works thanks to an overpressure inside the enclosure compared to the surrounding pressure.
After a pre-cleaning phase, in which, if possible, existing gases are expelled, the controller switches on the installed internal devices.
