5.2 Electrical Data
The ELB (earth leakage breaker), FUSE and S (main switch) must be installed to the each power source of outdoor unit. If
not, it may cause an electrical shock or a re.
Perform the electrical work according to the regulations of each region and this manual.
NOTE: Supply the power source of outdoor units and indoor units respectively.
(1) Power Supply Wiring
Supply the power sources to the each outdoor unit respectively. Power source wiring is fundamentally according to this
method.
(2) Electrical Characteristics
Note the following when selecting wiring:
● Use the charts below to select appropriate sized breakers / fuses / overcurrent protection switches and wiring in
accordance with local codes.
● Ensure communication cable is a minimum of AWG18 (0.82mm²), 2-Conductor, Stranded Copper.
