      Protection
      Battery Polarity Reversal If the battery is connected with reverse polarity, the rectifier remains in stand-by mode and gives error/warning message.
      Electronic Overload Protection Complete protection in case of output short circuit, overload, over-temperature
      Anti-Arcing When the battery is connected, no arcing is generated at the connectors
      Power-On Self-Test Every time the unit is powered, an automatic self-test of the power electronics and the control boards is executed in less than 10 seconds. In case of fault, the unit remains in safe stand-by mode and gives fault messages.
