Replacing the System Fans
The operation of the KISS 4U KTC5520 system is permitted only with a functional fan slide-in module!
Defective components may only be replaced by Kontron original spare parts:
Part number of the fan slide-in module: 1036-5056.
The fan slide-in module can be replaced during operation. This should only be carried out by a qualified
specialist or a suitably instructed user, who is aware of the associated dangers.
Keep your hands and fingers away from rotating parts of the fans. Before taking out the fan slide-in
module, wait until the fans have totally stopped.
To replace fan slide-in module, proceed as follows:
1.
Remove the filter mat holder as described in chapter 9.1 “Cleaning the Filter Mat” (step 1 to 3) and put it aside for
later reassembly.
2.
Loosen the two knurled screws of the fan slide-in module (Fig. 38, pos. 1)
3.
Pull the fan slide-in module out of the cabinet using the knurled screws to disconnect it from the internal fan control
socket (Fig. 39, pos. 4).
4.
Lift the fan slide-in module as shown (Fig. 38, pos. 2) out of the fan compartment (see Fig. 39).
