FOS 100
Prior to wall mounting, make sure that there are no concealed supply lines (power, water, gas,
telephone, coaxial or fiber cable) at the intended installation place. During operation, the
FOS 100 is markedly warming up, but this operating temperature is not dangerous at all.
However, to provide for unimpeded heat dissipation, the FOS 100 must not be installed into a
fully closed casing, lacking of a sufficiently dimensioned breather hole. For the same reason
the device shall also be protected from intensive heating, caused e.g. by heating appliances or
direct sun radiation. Further, do not expose the modem to a very humid or dusty environment.
The mounting instructions can be found on the drilling template. Initially, only the upper of
the two screws shall be inserted. For further mounting, the FOS 100 has to be opened. To
avoid contact with parts under voltage, make sure that the power supply unit is removed. The
device can be opened by inserting the screwdriver into the notches on either side of the cas-
ing, while pressing the snap-fits inwards. Remove the upper casing part. Hang up the bottom
part on the upper screw. In the centre of the PCB and bottom casing part there is an opening,
through which the lower bore hole becomes visible. Insert the second screw through the open-
ing and tighten it. Finally let the upper casing snap onto the bottom part.
