•
Check to ensure that the field supplied electrical components (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.
Use wires which are not lighter than the polychloroprene sheathed flexible cord (code designation 60245 IEC 57).

•
Ensure specifically that there is an Earth Leakage Breaker (ELB)
installed for the units (outdoor and indoor unit).
•
If the installation is already equipped with an Earth Leakage Breaker
(ELB), ensure that its rated current is large enough to hold the current
of the units (outdoor and indoor unit).

• 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).
