4.1.2 Minimum requirements of the protection devices
!
C A U T I O N
•
Ensure specifically that there is an Earth Leakage Breaker (ELB) installed for the units.
•
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.

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).
