Figure 5.7 Installation of the INT-TXK (steps 7 - 12)
1. If the LBB4502/xx transmitter is missing a stud to mount the new main PCB (2) of the
INT-TXK, paste the glue stud (1) from the upgrade kit to the bottom of the transmitter.
See inset in Figure 5.6 for the recommended pasting position.
2. Click the mains socket (3) in position in the new rear panel (4).
3. Fit the connectors (5) of the mains inlet wires (5A - brown, 5B - blue) and the earth wire
(5C) on the pins of the mains socket.
4. Mount the rear panel using the screws (6) and the (spring) washers (7).
5. Install the main PCB (2) using the screws (8) and the (spring) washers (9). If the
LBB4502/xx transmitter is provided with a stud to mount the main PCB, use the extra

6. On the new main PCB:
– Fasten the user interface cable (10).
– Fasten the power supply connector (11).
7. Mount the three distance studs (12A, 12B and 12C) of the analogue input/output PCB
through the orifices in the new main PCB.
8. Mount the analogue input/output PCB (13):
– Place the analogue input/output PCB on its distance studs (12).
– Fit the screws (14) with the (spring) washers (15).
– Carefully give the screws a few turns. Do not yet tighten the screws.
