To display this bar graph, press once. This display shows a “V” on the left and a line on the
right. The line on the right is a bar graph that shows the level of the voltage available at your
wall outlet and how the UPS is using this voltage. Here is what the graph means:
The input voltage is too low, so the UPS is boosting the voltage before providing
output to your equipment.
The input voltage is normal. The UPS is conditioning the power from your input
voltage before providing output to your equipment.
The input voltage is too high, so the UPS is in “buck” mode. In this mode, the UPS
reduces the voltage before providing output to your equipment.
To switch back to the normal display, press briefly twice. The first time you press this key,
the display will change to the Battery Charge bar graph. The second time you press the key, the
UPS will switch back to the normal display.
Displaying the Battery Charge Bar Graph:
The Battery Charge bar graph shows you how much the batteries are charged. To display this bar
graph, press to display the input voltage bar graph first; then, press once more to display the
battery charge bar graph. This display shows a “b” on the left and a line on the right. The line on
the right shows the battery charge. Here is what the graph means:
The battery charge is very low. If there is a power outage, the UPS will only run on
battery power for a short time before shutting down. If the UPS is receiving input
voltage from the wall outlet, it is charging its batteries.
The batteries are partly charged. If there is a power outage, the UPS can operate on
battery power for a short time. If the UPS is receiving input voltage from the wall
outlet, it is charging its batteries.
The batteries are fully charged (or close to being fully charged). If there is a power
outage, the UPS should be able to provide the full battery backup time (runtime) for the
equipment it is protecting. If the UPS is receiving input voltage from the wall outlet, it
is keeping the batteries charged.
To change back to the normal display, press the key briefly.
Note: When the UPS switches from battery power operation to normal (AC line) operation, the
battery charge bar graph may not be accurate for a few seconds. The UPS will
correct the graph after a few seconds.
