OPERATION
Be sure the power cord is plugged into an appropriately rated outlet.
Activate the INPUT ON/OFF Circuit Breaker to the “ON” position on the UPS.
Activate the SYSTEM ON/OFF Switch to the “ON” position on the UPS.
The system will go through a diagnostic test routine.
The green AC IN OK L.E.D. will flash several times before it illuminates solid.
The audible alarm will sound a short burst.
The AC INV L.E.D. will illuminate and the loads AC1-8 will illuminate.(if Load switches are in
the “ON” position).
Activate the SYSTEM ON/OFF Switch to the “OFF” position to discontinue system operation.
Turn off the devices you wish to plug into the UPS. Connect them to the output at the rear of the
unit. Do not exceed the output ratings of the system.
Activate the SYSTEM ON/OFF Switch to the “ON” position.
The system will go through a diagnostic test routine and test all the L.E.D.s.
Push and hold in the LOAD ON/OFF Switch for at least two seconds.
The AC OUTPUT L.E.D. will illuminate indicating output power is available at the rear panel
outlets.
Turn “ON” the Load Switches on the Control Panel.
Turn “ON” each of your devices.
Some of the four green L.E.D. LOAD indicators should illuminate. The amount of load is
determined by the actual number of indicators lit.
Each L.E.D. signifies approximately 25% of load capacity. If all four L.E.D.s illuminate, full load
has been achieved. If the red light illuminates, an OVERLOAD condition is present. If this
situation continues beyond three seconds, the unit will automatically shut off, discontinuing all
operation including the output to the load. The red FAULT L.E.D. will light and a continuous
alarm will be heard. The load must be reduced and the SYSTEM ON/OFF Switch will have to be
reset in order to return to normal operation.
If the system overheats or the INVERTER should fail, the unit automatically transfers power to
the BYPASS line to maintain uninterrupted power to the load. The red BYPASS L.E.D., above
the LOAD ON/OFF Switch, will light. A continuous alarm will sound and the red FAULT L.E.D.
will illuminate.
To escape this condition, the problem must first be corrected, then the SYSTEM ON/OFF Switch
must be reset.
The ALARM RESET Switch on the front panel of the UPS can be used at any time to silence the
audible alarm. This switch must be held in for at least two seconds before the alarm will quiet.
The FAULT L.E.D. above this switch will remain unchanged while operating this switch.
