6. Former version of the housing: lift the Module carefully out of the housing.
Current version of the housing: remove the fan and lift the module at the side marked with "A" or
untighten the clamps at the cable inlets and lift the module at the side marked with "A".
7. To mount the new Module, proceed in the reverse order. If the fan has been removed (current
housing version) it must be installed in the correct direction (flow of air to the outside). Further adjust-
ments or setting are not necessary. For the connection of the coaxial cables see Figure 4-5 on page
