BBU WIRING AND SETUP
1. Connect the positive (+) charger/controller lead
wire (red) to the positive (+) battery terminal (red).
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.
Figure 5: The battery input is inside the battery case.
Support the case when opening it. The support must be
at least 4" thick.
2. 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 '–'.
NOTICE: If the leads are reversed, the pump will run
backward and not pump water.
3. The float switch leads are not polarity sensitive;
connect the float switch leads to the 'Float Switch'
tabs on the charger/controller.
4. Test the float and the pump by lifting and holding
the float. 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.
5. To stop the pump, lower the float; after 25 seconds
the pump should stop, the 'PUMP STATUS' LED
should flash, and the buzzer should beep.
6. With the pump operating, test the 'SILENCED
ALARM' button; hold for one second; release.
The 'SILENCED AUDIBLE ALARM' LED should
illuminate and the buzzer should stop sounding. To
reset the buzzer (allow it to sound) and extinguish
the 'SILENCED AUDIBLE ALARM' LED, press the
'SILENCE ALARM' button again for one second.
Depress the 'SYSTEM TEST' button; hold it for one
second; release. The 'PUMP STATUS' LED should stop
flashing.
