INTRODUCTION
Keep this manual and the System Installation Guide in the folder mounted inside the
unit.
This unit is a microprocessor controlled PWM (Pulse Width Modulated) pure sine wave
based DC to AC power inverter utilizing MOSFET technology. It integrates a fully automatic
3-rate battery charger, a solid-state transfer system, control circuitry, self testing and
recording digital meter display, and maintenance free sealed lead calcium type batteries.
The system components are carefully matched to make the unit a completely self-contained,
fully automatic standby power source for operation on all types of lighting loads. The
batteries are sized and tested per UL-924 and Life Safety Code ANSI / NFPA 101, providing
emergency power for a minimum of 90 minutes.
If the duration of a power failure is greater than the batteries storage capability, the inverter
will automatically shut down when the battery voltage reaches 85% of the nominal DC
voltage. This feature protects the battery from being permanently damaged from a deep
discharge that could cause cell reversal. This battery protection feature is called "Low
Voltage Disconnect" or L.V.D.
When the AC power is restored after a full discharge, the system will be ready for another
power failure within 24hrs. If another power failure occurs before the 24-hour recharge time,
the run time will be decreased.
The front panel display incorporates an alphanumeric 2x20 LCD character display, LED
status indicators and a 4 x 4 keypad. All user interface functions are available from the front
panel assembly.
Utilizing a small footprint, this unit is for use with any lighting load including quartz, HID,
incandescent, fluorescent and halogen.
