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 unit must be made using two low-voltage terminal boards: GND, A, B. Connect “GND” on the terminal board of the indoor unit to “GND” on the terminal board of the outdoor unit. Connect “A+” on the terminal board of the indoor unit to “A” on the terminal board of the outdoor unit. Connect “B-” on the terminal board of the indoor unit to “B” on the terminal board of the outdoor unit. 1 ph 3 ph 1 ph 3 ph T T T T ON ON ON ON OFF 30mA N XXA N XXA N OFF 30mA N N XXA N XXA OFF 30mA N XXA N XXA N OFF 30mA N N XXA N XXA GND A B L1 L2 L3 N ⏚ MODBUS SE TNK GND A B B EBUS2 T 1 ph Single-phase power supply (depending on the model) 3 ph Three-phase power supply (depending on the model) a a Fig. 78 Once you have completed the connections between the indoor and outdoor units, put both electrical panels back into place.

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. 5.4.2 On-board installation Fig. 81 The system interface must be mounted on the indoor unit prior to connecting the BUS line. – Remove the screw (1) and open the front panel (2). 2 1 1 Fig. 79 – Connect the pair of wires to connector (2) while respecting the B-T polarity. – Detach the clips (3) and open the cover (4).
