3.3.3 Installation
Lifting the cabinet off the transport pallet
The applicable local guidelines regarding the transportation of the cabinet from the transport
palette to the installation location must be observed.
A crane transport assembly (option M90) can also be fitted on the top of the cabinet.
Installation
Four holes for M12 screws are provided on each cabinet panel to secure the cabinet to the
ground. The fixing dimensions are specified on the dimension drawings enclosed.
3.3.4 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 flush-mounted with the cabinet unit and is fitted using spacers at a distance of 250
mm above the top 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 by means of the four holes for the crane hooks in the cabinet. Fitting hoods
increases 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 by means of the four holes for the crane hooks in the cabinet.
Fitting hoods increases the height of the cabinets 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 by means of the four holes for the crane hooks 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.
