Maintenance
Operation
During normal operation, AC power is supplied to the AC ballast/driver through the ELI-S-100 and the batteries charge.
Connecting the inverter connector wires (red and white) enables the emergency circuit and supplies power to the control
/monitor circuit. When AC power fails, the ELI-S-100 automatically switches to emergency mode, keeping the load
illuminated for a minimum of 90 minutes. When AC power is restored, the ELI-S-100 returns to charging mode. The unit
can also detect an abnormal load condition (open or shorted load) during emergency mode operation and will protect the
inverter from damage.
Always turn off AC power to the equipment and open the inverter connector inside the case before servicing. Servicing should
be performed only by qualified service technicians. Use only manufacturer supplied replacement parts.
Although no routine maintenance is required to keep the emergency Lighting Inverter functional, it should be checked
periodically to ensure that it is working.
Figure 7 shows an example of a branch circuit containing 5 luminaires, 3 of which are powered through an Emergency
Lighting Inverter. During normal AC run mode, the power from the switched hot and dimmer voltage is passed through to
the three “Emergency” fixtures. The unswitched hot charges the battery. During a power failure, the Emergency Lighting
Inverter powers the “Emergency” fixtures for a minimum of 90 minutes, at a power level set by the Emergency Lighting
Inverter’s dimming output level. In this example, each luminaire can draw a maximum of 33 Watts, to total no more than
100 Watts.
Battery: The Battery supplied with this equipment requires no maintenance. However, it should be tested periodically
and replaced whenever it will no longer operate the connected fixtures for the duration of a 90-minute test. The battery
supplied has a life expectancy of 4 years when used in normal ambient temperature of 72 degrees F.
Fuse: The fuses contained within this product are field replaceable. For fuse locations see illustration 1. To replace fuses,
remove AC Power from the product and disconnect the inverter connector. Ensure fuse F201 is replaced by Little Fuse
0314015.MXP or equivalent 15 A, 125 VDC. Ensure fuse F101 is replaced by Little Fuse 0209005.MXP or equivalent 5 A,
350 VAC.
>
After installation is complete, apply AC power and join the inverter connector inside the case then screw the front
cover to the case.
>
At this point, power should be connected to both the AC ballast and the ELI-S-100, and the Charging Indicator
Light on the test switch should illuminate indicating the battery is charging.
>
A short-term discharge test may be conducted after the Emergency Lighting Inverter has been charging for 1 hour.
Charge for 24 hours before conducting a long-term discharge test. Refer to OPERATION.
STEP #7
JOIN THE INVERTER CONNECTOR & APPLY POWER
! REFER ANY SERVICING TO QUALIFIED PERSONNEL !
Note:
Mark each designated emergency fixture with provided warning labels, 10 provided.
Testing:
The following schedule is recommended
1.
Visually inspect the charging indicator light monthly. It should be illuminated.
2.
Test the emergency operation at 30-day intervals for a minimum of 30 seconds by pushing the illuminated
test switch located at the top of the unit.
3.
Conduct a 90-minute discharge test once a year.
