BBU WIRING AND SETUP
1. Connect the positive (+) charger/controller lead wire (red)
to the positive (+) battery terminal (red).
2. Connect the negative (–) charger/controller lead wire
(black) to the negative (–) terminal (black) on the battery.
If you are using two batteries, use the set of optional
terminals and connect the second battery.
Use lead wires (not included) to connect the positive
(+) charger/controller terminal to the positive (+)
battery terminal and the negative (–) charger/
controller terminal to the negative (–) battery
terminal.
3. The backup pump leads are polarity sensitive. Connect
the positive pump lead to the terminal labeled Pump ‘+’ and
the negative pump lead to the terminal labeled Pump ‘–’.
NOTE:
If the leads are reversed, the pump will run
backward and not pump water.
4. The float switch leads are not polarity sensitive. Connect
the float switch leads to the ‘Float Switch’ tabs on the
charger/controller.
5. Test the float and the pump by lifting and holding the float.
The system alert LED will blink while the float is up. The
‘Pump Status’ LED will light continuously and the buzzer
will beep steadily.
The pump should start after 3 seconds. If the pump does
not run, check all the connections and remake them as
necessary.
6. To stop the pump, lower the float. After 25 seconds the
pump will stop, the ‘Pump Status’ LED will flash, and the
buzzer will beep.
7. With the pump operating, test the ‘SILENCE ALARM’
button by holding for one second before releasing. The
‘Alarm Silenced’ LED should illuminate and the buzzer
should stop sounding.
To reset the buzzer (allow it to sound) and extinguish the
‘Alarm Silenced’ LED, press the ‘Silence Alarm’ button
again for one second.
Depress the ‘Test System’ button; hold it for one second;
release. The ‘Pump Status’ LED should stop flashing.
