TROUBLESHOOTING
NOTES:
1) Follow local codes and regulations when selecting field wires.
2) This equipment can be installed with a Ground Fault Circuit Interrupter (GFCI), which is a recognized measure for
added protection to a properly grounded unit. Install appropriate sized breakers / fuses / overcurrent protection
switches, and wiring in accordance with local, state and NEC codes and requirements. The equipment installer is
responsible for understanding and abiding by applicable codes and requirements.
3) Total operating current should be less than 12A.
4) Fuse should be slow blowing capability.
● This equipment can be installed with a Ground Fault Circuit Interrupter (GFCI), which is a recognized
measure for added protection to a properly grounded unit. Install appropriate sized breakers/ fuses/
overcurrent protection switches, and wiring in accordance with local, state and NEC codes and
requirements. The equipment installer is responsible for understanding and abiding by applicable codes
and requirements. Check the recommended size of ELB shown in Table 3.1.
Select high-sensitive high speed ELB or GFCI when the rated sensitive current is less than 30mA. (The
motion time should be within 0.1 second.)
● 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.
