Operation (Special Conditions)
OPERATION ON BYPASS—VOLTAGE OUT OF RANGE
While in Bypass Mode, the UPS monitors the input voltage, which on Bypass equals the
output voltage. If the output voltage passes out of an acceptable range (between 15% higher
and 20% lower than nominal), the UPS displays the condition on its LCD and stops
supplying output power to its load. If power levels return to an acceptable level, the UPS
resumes supplying power to the load, and its LCD reports that output voltage was too high
or too low at one time, but has returned to nominal.
OPERATION ON OVERLOAD
When the UPS detects an output overload, it will commence a countdown (the length of
time depending on the severity of the overload). If the UPS is still overloaded at the end
of the countdown, the UPS will automatically shut down and go into Bypass Mode.

LCD DISPLAY SELECT SWITCH
Momentarily press the “SELECT” switch on the front panel to browse through different
power readings on the LCD Display. The LCD Display will show which one of four
operational modes your UPS is currently in: Normal, Economy, On-Battery, or Bypass.
Also, as you press the “SELECT” switch, the LCD Display will browse through load, input,
bypass, output and battery conditions.
