2.2.2 Mounting an interface module in the transmitter housing
: Before opening the transmitter housing, make sure that the mains power and all other connections are disconnected!
: ICs and many other electronic components are susceptible to electrostatic discharge (ESD). Take preventive measures when
handling the interface modules. Keep the PCBs as long as possible in their protective packing. Wear an anti-ESD bracelet.
Follow the instructions below to mount an interface module in the transmitter housing. The numbers refer to Figure 2.5, Figure
2.6 and Figure 2.7.
1. Remove the top cover of the transmitter housing.
2. Remove the interface module slot cover (4) at the back of the transmitter. Keep the screws (7).
3. Remove the front plate (2) of the interface module (1). Keep the screws (5). The front plate is not used.
4. Remove the screws (6) that connect the back plate (3) of the module to the PCB. Keep the screws.
5. Mount the slot cover (4) and the module's back plate (3) to the module's PCB. Use the screws from step 4.
6. Insert the module (1) (with the components faced down) into the transmitter housing and push it firmly into the PCB
connector (9).
7. Fasten the slot cover (4) to the back of the transmitter housing. Use the screws (7) from step 2.
8. Fasten the module's PCB to the distance studs (8). Use the screws (5) from step 3.
9. Close the transmitter housing.
: To prevent damage to the PCB connectors (9), be sure that the connectors are aligned properly before pushing the module in.
