When this light is on (steady, not blinking), the UPS is using the utility power it
receives when you plug it in. The UPS conditions this power and protects your
equipment from power problems. The display shows the percent of the UPS’ power
that your equipment is using.
If the green light is blinking while the yellow light is on, utility power is available, but the UPS is
not using it because of high or low voltage or other power problems. If the input power problem
continues, the UPS will continue to run on battery power until it uses up its battery backup time.
To adjust the UPS’ sensitivity to utility power problems, see
Section 7E .
When this light is on (steady, not blinking), the UPS is using its batteries to
provide power to your equipment. This happens during a power outage or when there
is a severe problem in the power your UPS is receiving. The display flashes the
number of minutes the UPS can provide battery power (backup time or runtime), and
the UPS beeps regularly.
If this light is on while the green light is blinking, the UPS is running on battery power because
of a problem in the input power, not because of a power outage. The UPS must run on battery
power to provide the best power to your equipment. To adjust the UPS’ sensitivity to these power
problems, see
Section 7E .
When this light is blinking, the UPS is performing a battery test to make sure it can provide
enough backup time. The UPS does the battery test automatically every 30 days; you can also
start a test by pressing and holding the key. (See
Section 4A .)
When this light is on or flashing, the UPS is warning you that something is wrong.
The UPS helps you identify the source of the problem in two ways:
1) by flashing a two-letter alarm message, and
2) by sounding the Morse Code for an alarm letter.
The Alarm section on page 17 will help you identify the alarm using either the alarm message or
the Morse Code. To silence the alarm, press and hold . The display will show “Sh” briefly, and
the red light will be steady (not blinking or flashing).
120-volt models have a light on the back panel in the lower right corner.
If this light is on, the outlet the UPS is plugged into needs repair. Plug
the UPS into another outlet and call an electrician to repair the faulty
outlet.
