Do NOT connect the battery backwards; charger damage may result
The voltmeter will show battery voltage as soon as the DC connection is completed.
Check the voltmeter
he DC connection has been made. If the meter reads zero or is deflecting below zero, reverse
the polarity of the battery connections.
Alarm Connections
F3 chargers are supplied with one of three following alarms configurations:
