For external cooling, the module heatsinks protrude through the mounting plane
in the cabinet which allows the power loss to be dissipated to an external coo-
ling circuit.
An opening can be provided in the mounting plate for each module or for the
complete module group. If an opening is used for the complete module group,
then the specific module mounting frames must be used. The appropriate
mounting frames (Order No.: 6SN1162–0BA04–0EA0) must always be used for
the 300 mm modules. The dimension drawings for the openings are described
in Section 13.
The mounting frames should be mounted from either inside the cabinet or the
rear side. This then guarantees the required EMC mounting surface
Note
The dimensions of the openings for the reinforcing lugs have different lengths.
Be sure that all of the modules are mounted/installed in the same way.
Sealing The reinforcing lugs of the mounting frames, which are rounded–off towards the
rear are provided with a seal at both sides. A sealing material must be used
where the edges of the mounting frame come into contact with the mounting
plate (e.g. Terostat–96 from Teroson). Degree of protection IP 54 is achieved
when the sealing material is correctly applied.
The fan cable must enter the cabinet through a PG gland so that the degree of
protection is maintained.
The mounting plate should be sealed with respect to the rear cabinet panel so
that an enclosed space or duct is obtained. Depending on how the cabinet is
mounted (free–standing or installed in the machine), this must be cooled
through the roof/floor assembly or rear panel.
