! CAUTION
• Ensure specically 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).
? NOTE
• 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).
