Battery Charge Meter
The 5-LED display on the right side of the BORIS unit shows the present charge of UPS’s
battery as a percentage of the battery’s capacity. When all five LED’s light, the battery is
fully charged. When the lowest LED is flashing, the battery can supply less than 2 minutes
of run time for the load.
The example shows the battery charge level between 72% and 96% of full charge.

Line Voltage Meter
If the “On/Test” pushbutton is held for 4 to 5 seconds, the lights on the right side of the
front panel form a bar graph showing the input line voltage. Note: The UPS will start a
self-test as part of this procedure. The self-test does not affect the voltage display.
This example shows the input line voltage to BORIS is between 114 VAC and 124 VAC.

AVR Trim
This indicator comes on to indicate that the UPS is compensating for a high voltage level.
The BORIS automatically corrects high and low voltages so that the loads receive voltage
within the normal range.
4.6.2
On Line
This light indicates BORIS is operating normally and power is present at B1-B2. The light
blinks when BORIS’ self-test feature is initiated at “power up” or when either the Test or
Reset buttons are pressed.
