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.
Screws and other small components that fall into the cabinet or the installed components
during installation of the canopies or hoods can cause substantial damage during operation
and must therefore be removed reliably before the drive cabinet is connected.
Description
The degree of protection can be increased to IP21 by fitting an additional canopy. The
canopy is mounted using spacers at a distance of 250 mm above the top cover of the
cabinet. As a result, all cabinets with a canopy are approx. 270 mm (250 mm + height of the
canopy) higher.
Systems with degree of protection IP23 are supplied with additional hoods, as well as plastic
ventilation grilles in the air intake and the air outlet and additional plastic filters (mess width:
1 mm) in the air inlet (doors). 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.
Systems with degree of protection IP43 are supplied with additional hoods, as well as plastic
ventilation grilles and plastic filters (mess width: 1 mm) in the air inlet (doors) and air outlet
