NOTES:
1) 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 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 (Ground Fault Circuit Interrupter) 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.
