A VOLTMETER BEFORE ANY OPERATION ON A SYSTEM.
THE DC OUTPUT IS EQUIPPED WITH FILTERING CAPACITORS, DANGEROUS
VOLTAGES CAN REMAIN EVEN IF THE CHARGER IS STOPPED AND THE BATTERY
DISCONNECTED. ALWAYS CHECK THE ABSENCE OF VOLTAGE ON THE DC
CIRCUITS BEFORE TO START ANY WORKS ON THE SYSTEM.
DANGEROUS VOLTAGES CAN REMAIN ON THE SYSTEM EVEN IF IT IS SWITCHED
OFF AND INSULATED FROM MAINS AS LONG AS BATTERY IS CONNECTED.
