● 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 cable
for communication cable. Do not use any cable with more than two conductors. Twisted pair or
shielded cable can be used in environments with excessive electrical noise to reduce the possibility of
communication 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 and
Maintenance Manual", and the dedicated electrical circuit that must be used.
● Outside of the indoor unit, installation of the power supply wiring, communication cable, and wired
controller cable should be spaced as far apart as possible.
NOTICE
NOTES:
1) Follow local codes and regulations when selecting field wires.
2) Select a GFCI with an activation speed of 0.1 sec. or less.
3) Total operating current is less than 12A.
