⇒ The amber REPLACE BATT L.E.D. will flash and the audible alarm will sound.

The microprocessor will run a battery diagnostic check.

⇒ The Control Panel audible alarm will sound after the test.

If the battery is found to be fatigued compared to predetermined or typical battery parameters,
the amber REPLACE BATT L.E.D. will illuminate, suggesting the user replace the batteries. If
the SNMP battery test function is enabled, the microprocessor automatically runs this test. The
user will be alerted of a faulty battery or battery not connected to the UPS.

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 with the

exception of the COLD START L.E.D.

⇒ 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.

To DC Start the unit:

⇒ Activate the UPS Front Panel SYSTEM ON/OFF Switch to the “ON” position. Activate the

Control Panel POWER ON switch to the “ON” position.

⇒ Push and hold the COLD START switch on the UPS until the alarm sounds once.

⇒ Push and hold in the LOADS ON/OFF Switch for at least two seconds. You can use either

Loads ON/OFF switch from the UPS or the Control Panel.
