Mounting
frame
Seal the mounting frames
with respect to one another
and to the rear cabinet panel
(e.g. using Terostat–91
made by Henkel).
The sealant (preferably
inside the cabinet) should be
applied around the
circumference so that
degree of protection IP54 is
ensured.
First mount the frame and
then seal!
It should be checked that the
foam rubber seal is tight – if
required, seal!

Note
Refer to Fig. 2-9 for the air flow direction and the dimension drawing in
Chapter 12 for the ventilation space. The dimensions of the installation frame
are presented in the dimension drawing in Chapter 12.
Notice
For external heatsinks and fans, a high degree of pollution restricts the module
cooling. This can cause the temperature monitoring function in the power
module to respond. The heatsinks and fans must be checked for accumulated
dirt at regular intervals.
Clean when required!
