Battery Guard
• To protect the batteries from complete discharging, the RCCA920 is equipped with
an integrated battery monitoring system.
• To protect the batteries, the monitoring system will switch the unit off once the
battery voltage drops below the preset cut-out value. The operation starts again
after the unit is connected to an external power source and the batteries are
charged again. This cut-in process may take several minutes. Leave the appliance
switched on during this period.
• The battery guard is protected by a 10A fuse located in the compressor
compartment.
