Follow local codes and regulations when selecting field wires.2. Select the GFCI with activation speed of 0.1 sec. or less.3. Total operating current is less than 12A.● Check for the recommended size GFCI shown in the table 8.1.● Between indoor and outdoor units, use dual-conductor, AWG18 (0.82mm 2 ) stranded copper cablefor communication cable. Do not use any cable with more than two conductors. Twisted pair orshielded cable can be used in environments with excessive electrical noise to reduce the possibility ofcommunication errors between system components. Total cable length should not exceed 3281 ft (1000m).● Select the wiring size, GFCI in accordance with the regulations for each region, the "Installation andMaintenance Manual", and the dedicated electrical circuit that must be used.● Outside of the indoor unit, installation of the power supply wiring, communication cable, and wiredcontroller cable should be spaced as far apart as possible.Heat Pump System Heat Recovery System8.2.2 Details of Electrical Wiring ConnectionThe electrical wiring capacity of the outdoor unit should be referred according to the "Installation andMaintenance Manual" for the outdoor unit. Adjusting the DIP switches may be required depending on thearrangement with the outdoor unit.Select wiring capacity according to the table 8.1. Install a Ground Fault Circuit Interrupter (GFCI) andmain switch as shown in each of the system diagrams below.NOTICEOutdoorUnitIndoorUnitSwitchboxOutdoor UnitPower SupplyIndoor UnitPower SupplyIndoorUnitIndoorUnitGFCIMainSwitchGFCIMainSwitchRefer to the “Installation and Maintenance Manual”for the connected outdoor unit for details of wire,GFCI and main switch for outdoor unit.Outdoor UnitPower SupplyOutdoorUnitChange-OverBoxIndoor UnitPower SupplyIndoorUnitSwitchboxIndoorUnitIndoorUnitGFCIMainSwitchGFCIMainSwitchRefer to the “Installation and Maintenance Manual”for the connected outdoor unit for details of wire,GFCI and main switch for outdoor unit.
