OPERATION
When 120VAC household power is available to the Primary Sump Pump
Backup Power System, household power is directly routed through to both of
the outlet receptacles. When the unit is powered ON (the “Power” indicator
LED will be BLUE), the unit will charge the connected 12VDC Deep Cycle
Battery if needed. The “Charge” status indicator LED will be RED while
charging the battery. The “Full” status indicator LED will be BLUE once the
battery is fully charged. When AC power is lost, the Primary Sump Pump
Backup Power System will automatically activate and convert the 12VDC input
to 120 VAC pure sine wave output at both of the outlet receptacles.
The “Fault” status indicator LED will turn RED when the Primary Sump Pump
Backup Power System is overloaded, overheating, receiving low household
voltage, or has a short circuit.
Multiple 12VDC Deep Cycle Batteries may be
connected in parallel. A PumpSpy Maintenance
Free AGM Deep Cycle Battery is recommended.
