Notes
1. To be EN378:2016 compliant, the leak detection sensor must be powered from a separate
power source to that of the FCU.
2. If EN378:2016 compliance is not required, it is possible to power the sensor direct from
CN61 of the indoor PCB, using the supplied wiring loom.
3. When using the External power supply option TCB-LD24V, then please refer to
the installation diagram supplied with the product.
4. Power supply wire and interconnecting wires are procured locally.
5. Using the specified wires, ensure to connect the wires and fix wires securely, so
that the external tension to the wires does not affect the connecting part of the terminals.
Incomplete connection or fixation may cause a fire, etc.
6. Be sure to connect earth wire (grounding work) on indoor PCB. Incomplete grounding
causes an electric shock. Do not connect ground wires to gas pipes, water pipes, lightning
rods or ground wires for telephone wires.
7. Appliance shall be installed in accordance with national wiring regulations.
Capacity shortage of power circuit or incomplete installation may cause an electric shock
or a fire.
