Fitting additional canopies (option M21) or hoods (option M23, M43, M54)

To increase the degree of protection of the cabinets from IP20 (standard) to IP21, IP23,
IP43, or IP54, additional canopies or hoods are supplied. These must be fitted once the
cabinets have been installed.
Description
The degree of protection can be increased to IP21 by fitting an additional canopy. The
canopy is mounted protruding above the cabinet on spacers, 250 mm above the top cover of
the cabinet. As a result, cabinets with a canopy are 250 mm higher.
Cabinet units with degree of protection IP23 are supplied with additional hoods, as well as
plastic ventilation grilles and 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. Hoods increase the height of
the cabinet by 400 mm.
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 on a regular basis according to the prevailing ambient conditions.
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 on a regular basis according to the prevailing ambient conditions. Filters can be
fitted and replaced from outside the cabinet relatively easily.
Note
Installing the canopy or hood at a an early stage!
It is recommended to attach the canopy or hood at an early stage to prevent foreign matter
entering the cabinet devices.
