Degree of protection IP43
Cabinet units with degree of protection IP43 are supplied with additional hoods, as well as
plastic ventilation grilles and close-meshed braided plastic in the air inlet (doors) and outlet
(hoods). The hoods are flush with the cabinets at the side and front and have a recess at the
rear so that air can escape even if the cabinet is wall mounted. Air escapes from the front
and back. The hood is secured via the four crane hook holes in the cabinet. Attaching the
hoods increases the height of the cabinet units by 400 mm.
Compliance with degree of protection IP43 requires an intact filter medium, which must be
serviced at regular intervals depending on the prevailing ambient conditions.
Degree of protection IP54
Cabinet units with degree of protection IP54 are supplied with additional hoods, plastic
ventilation grilles, and a filter medium in the air inlet (doors) and outlet (hoods). The hoods
are flush with the cabinets at the side and front and have a recess at the rear so that air can
escape even if the cabinet is wall mounted. Air escapes from the front and back. The hood is
secured via the four crane hook holes in the cabinet. Hoods increase the height of the
cabinet by 400 mm.
Compliance with degree of protection IP54 requires an intact filter medium, which must be
replaced at regular intervals depending on the prevailing ambient conditions. Filters can be
fitted and replaced from outside the cabinet relatively easily.
Note
Early mounting of the canopy or hood!
It is recommended to attach the canopy or hood at an early stage to prevent foreign matter
entering the cabinet devices.
