(mains power switches, circuit breakers, wires, connectors and wire
terminals) have been properly selected according to the electrical
data indicated on this chapter and they comply with national and local
codes. If it is necessary, contact with your local authority in regards to
standards, rules, regulations, etc.
• Use a dedicated power circuit for the indoor unit. Do not use a power
circuit shared with the outdoor unit or any other appliance.
N O T E
• Electric fuses can be used instead of magnetic Circuit Breakers (CB).
In that case, select fuses with similar rated values as the CB.
• The Earth Leakage Breaker (ELB) mentioned on this manual is also
commonly known as Residual Current Device (RCD) or Residual
Current Circuit Breaker (RCCB).
• The Circuit Breakers (CB) are also known as Thermal-Magnetic
Circuit Breakers or just Magnetic Circuit Breakers (MCB).
Use wires which are not lighter than the polychloroprene
