INSTALLATION
WIRING THE BACKUP NANO INVERTER
> Use the wiring diagram found on page 4 as reference.
> Connect the AC power source leads (Switched and Unswitched) to the input of the backup nano inverter.
> Connect the output leads of backup nano inverter to the AC ballast/driver.
> Wire the AC ballast/driver with the lamp in accordance with manufactures installation instructions. No ballast/
driver is necessary for single dimmable lamp (under 10VA) application.
> Make sure all connections are in accordance with the National Electrical Code, Canadian Electrical Code and
any local regulations.
> Connect the Test Switch/Charging Indicator Light by matching violet/white and brown/white leads. Mount in
a readily visible location.
> In a readily visible location, attach the label “CAUTION–This Unit Has More Than One Power Connection Point.
To Reduce The Risk Of Electric Shock, Disconnect Both The Branch Circuit-Breakers Or Fuses And DC Power
Supply (Backup Ballast Inverter Connector) Before Servicing.”
STEP #3
STEP #4
JOIN THE INVERTER CONNECTOR & APPLY POWER
> After installation is complete, apply AC power and join the blue connector.
> At this point, power should be connected to both the AC ballast and the backup nano inverter, and the Charg-
ing Indicator Light should illuminate indicating the battery is charging.
> A short-term discharge test may be conducted after the backup nano inverter has been charging for 1 hour.
Charge for 24 hours before conducting a long-term discharge test.
Refer to OPERATION.
During normal operation, AC power is supplied to the AC ballast/driver through the backup nano inverter and the inverter charges its
internal battery. Connecting the blue connector wires enables the emergency circuit and supplies power to the
control/monitor circuit. The backup nano inverter detects AC input line voltage (120 or 277 VAC, 60 Hz) and automatically sets the
output voltage during emergency mode.
When AC power fails, the backup nano inverter automatically switches to emergency mode, keeping the load illuminated for a
minimum of 90 minutes. When AC power is restored, the backup nano inverter returns to charging mode. The backup nano inverter
consists of a low-battery voltage disconnect which is reset when AC power is restored. The unit can also detect an abnormal load
condition (open or shorted load) during emergency mode operation and will protect the backup nano inverter from damage.
OPERATION
MAINTENANCE
Although no routine maintenance is required to keep the backup nano inverter functional, it should be checked periodically to ensure
that it is working. The following schedule is recommended:
1. Visually inspect the Charging Indicator Light monthly. It should be illuminated.
2. Test the emergency operation of the fixture at 30-day intervals for a minimum of 30 seconds.
3. Conduct a 90-minute discharge test once a year. The lamp should operate for at least 90 minutes.
