XC10 provides EN54-2 option with requirements "Total loss of power". This option
is mainly mandatory in France. When selected, "System fault" led and buzzer is
activated continuously for at least 1 hour after low discharge battery switch off (in
case the battery voltage fails below 21 V).
This option can be selected by wiring the +BAT terminal to the positive voltage of
batteries (use of remaining power of the battery).
