SELF TEST
The self test feature is useful to verify the correct operation of the UPS and the condition of the batteries. With the UPS in the AC normal mode, press and hold the On/Off/Test Button for four beeps, then release the button. The UPS will perform a ten-second self test. During the self test, the UPS will switch to battery power and the On-Battery LED will illuminate and the audible alarm will sound. The length of the test that is automatically performed every two weeks is longer than the start-up or user invoked test. This test will run for approxi- mately fifteen-seconds to measure the battery’s capability to provide an ac- ceptable amount of runtime. If the UPS fails a self test, one of the LEDs will remain illuminated indicating the type of problem. NOTE: The UPS will auto- matically perform a self test on start-up and every two weeks.
DIP SWITCH SETTINGS
The DIP Switch setting may be changed by the user to set the desired Inverter (On-Battery) output voltage. The DIP Switch must be set to the desired Inverter (On-Battery) output voltage and then the UPS must be turned off and restarted to reconfigure the microprocessor and save the changes. The Inverter (On- Battery) output voltage setting can be either 120VAC (default) or 127VAC. Chang- ing the Inverter (On-Battery) output voltage to 127VAC, will also change the Buck setpoint from 130VAC (default) to 137VAC.

LOAD SHEDDING FUNCTION
The output receptacles are electrically wired into two segments to support the "Load Shedding Function". The user can control the two segments individually or both at the same time. The Load Shedding Function is controllable by the Power Monitoring Software or the SNMP card.
ALARMS
ON BATTERY
When the UPS is operating on the batteries, the On-Battery LED will illuminate and the audible alarm will sound once every ten-seconds. The alarm will stop once the UPS returns to the AC normal mode.
LOW BATTERY WARNING
The UPS will sound two beeps every five-seconds when the battery reserve runs low. This condition will continue until AC returns or the UPS shuts down from battery exhaustion.
UPS FAULT
When the UPS detects a hardware fault, the Fault LED will illuminate and the UPS will sound a constant alarm. The fault condition, in some instances, may be reset by turning the UPS off and then on.
