When protection takes place the
inverter switches off automatically.
Before restarting the inverter it is
preferable to detach all appliances.
The protection curve, shown in Figure

Output current is reduced if exceeding
the indicated threshold. Output
voltage remains sinusoidal till peak
current limiter threshold is reached.

Inverter switches off automatically.
Before restarting the inverter it is
preferable to detach all appliances.
11.5.4 Peak Current Limiter
Threshold

Inverter clips the output current in
order to keep the absolute peak value
inside a safety region.

When temperature overcomes the
fixed threshold of 55±5°C on the heat
