Configuration
For external cooling, the module heatsinks extend through the mounting plane
in the electrical cabinet and can therefore dissipate power loss into an external
information
cooling circuit.
The breakout in the mounting panel can be made for each module or also for a
complete group of modules. For a breakout for the complete group of modules,
the specific mounting frames for the modules should be used. For 300 mm wide
modules, the appropriate mounting frame must be used (Order No.:
6SN1162–0BA04–0EA0). The dimension drawings for the breakouts are pro-
vided in Chapter 12.
The mounting frames should be installed from the inside of the cabinet or from
the rear. This also then guarantees the necessary mounting surface for EMC.
Note
The dimensions of the recesses for the reinforcing ribs have different lengths.
Ensure that the modules are mounted/installed in a standard way.
Seal
The reinforcing ribs of the mounting frames, that are rounded–off towards the
rear, have seals on both sides. A sealant (e.g. Terostat–96 made by Henkel)
must be used to seal the edges of the mounting frames in contact with the
mounting panel. Degree of protection IP 54 is achieved when the sealant is cor-
rectly applied.
Mounted fans for
The fan cable must be fed into the electrical cabinet using a PG gland to ensure
300 mm wide that the degree of protection is maintained.
modules
The mounting panel must be sealed at the rear panel of the electrical cabinet so
that a closed space or duct is created. Depending on how the cabinet is
mounted (free–standing or installed in the machine), this must be cooled/venti-
lated via the roof/base assembly or the rear panel.
Make sure that the air inlet is unobstructed. The distance to the side walls must
be at least 50 mm.
Fans must not draw in any air contaminated with cooling lubricant nor must they
be sprayed with cooling lubricant, as this will considerably reduce their service
life because of them sticking and cooling ducts can become clogged.
For further information refer to the device–specific technical user documenta-
tion.
