5.3 Example of electrical connection between indoor and outdoor units Electrical connections Before carrying out any work on the system, shut off the power supply at the main switch. The electrical connection between the indoor and outdoor units must be made using the two low-voltage terminal boards: G and S. Connect “G” on the indoor unit terminal board with “G” on the outdoor unit terminal board. Connect “S” on the indoor unit terminal board with “S” on the outdoor unit terminal board. T ON XXA* N N 2A N 2A OFF 30mA N S G ATGBUS G S ...

Keep the high- and low-voltage cables separate. 38 / EN

Electrical connections 5.4 Installing the system interface Note: when installing cascade systems, to install the system interface refer to the relevant dedicated manual. Positioning The system interface detects the room temperature. This factor must be taken into account when choosing its position. We recommend positioning the appliance far from heat sources (radiators, direct exposure to sunlight, fireplaces, etc.). We also advise against positioning it near draughts or external openings that could affect the operation of the system interface. The interface must be placed at least 1.5 m above the floor. a Installation should be performed by a qualified technician. Before installing the appliance, ensure that the electrical power supply is disconnected. 5.4.1 Wall installation The SENSYS HD system interface must be fitted to the wall prior to connecting the BUS line. – Open the holes required for fixing. – Fix the base of the device to the box on the wall using the screws (1). – Position the system interface on the base, pushing it slightly downwards. Fig. 60 Signal sending, receiving, and decoding is carried out using BUS protocol, which ensures the interaction between the system and the interface. Connect the cables to the terminal board located in the system’s indoor unit panel. NOTE: Use a shielded cable or a twisted-pair cable to connect the system interface and the indoor unit so as to avoid interference problems. B T 1 Fig. 58 – Connect the pair of wires to connector (2) while respecting the B-T polarity. B T Blue Orange Fig. 61 B T BUS B T 2 Fig. 59 B T Blue Orange 39 / EN
