CAUTION
Cabinet Modules do not fulfill the requirements for IP20 until they have been closed off by
installing a side panel on the right (option M26) and a side panel on the left (option M27).
The cabinet units are installed in accordance with the dimension drawings supplied. The
clearance between the top of the cabinet and the ceiling is shown in the diagram below.
Additional dimensions must be taken into account for the M06 (cabinet base) and M07
(cable-marshaling compartment) options.

Note
Further dimensions can be found in the relevant dimension drawings on the enclosed
customer CD.
The cooling air for the power unit is drawn in from the front through the ventilation grilles in
the lower part of the cabinet doors. The warmed air is discharged through the perforated top
cover or the ventilation grilles in the hood (with options M23/M43/M54 for degrees of
protection IP23/IP43/IP54). Cooling air can also be supplied from below through raised floors
or air ducts, for example. To allow this, you have to create openings in the sectioned base
plate.
