CHAPTER 3. INSTALLATION 28
3.2 Electrical Installation
In single-phase installations, the line phase wire must be protected by a circuit
breaker. Furthermore, the line phase wire must be connected to the phase input
connector of the inverter and the line neutral to the neutral input connector of the
inverter.

In the case of two-phase installations, it is mandatory to use a 2-pole circuit breaker,
because in case of a short circuit both phases of power supply are protected.
