6.3 Voltage Programming Button
The PowerSure PSI contains a Voltage Programming button that allows the operator to select
the nominal mains voltage. This setting changes the mains transfer points (low and high) of
the UPS and the nominal output voltage when operating in Battery mode. The operator can
select between 220, 230 and 240VAC output. The factory-default setting is 230VAC.
The Voltage Programming button is a push button type and is behind the plastic bezel on
the front panel of the UPS. To access the button, the front bezel must be removed.
6.4 Load Level Indicators—4 green, 1 amber
The Load Level Indicators display the approximate electrical load placed upon the UPS.
The UPS Load Level Indicators are displayed in 25% increments as shown in Figure 11.
Figure 11 Load level indicators—4 green, 1 amber
Upon detection of an output overload condition, the amber overload (>100%) indicator flashes and an
audible alarm activates. If the UPS shuts down due to an overload condition, the amber overload
(>100%) indicator illuminates (see 11.0 - Troubleshooting for details).
6.5 Battery Level Indicators—5 green
The Battery Level Indicators display the approximate battery capacity.
The approximate battery capacity is displayed when the UPS is operating in Normal, Buck/Boost, or
Battery mode.
The Battery Level Indicators are displayed in 20% increments as shown in Figure 12:

The PowerSure PSI is equipped with automatic and remote battery test features. The automatic test
occurs every 14 days if mains has not been interrupted; this option may be configured by the user.
Should the battery fail this test, the amber Battery Indicator will be illuminated and an alarm will
sound (see 11.0 - Troubleshooting for details).
The remote test feature functions with MultiLink 3.x software and can remotely initiate the battery
test.
6.6 AC Input Indicator—Green
The AC Input Indicator illuminates when mains power is available and within the input specifica-
tions.
6.7 Buck/Boost Indicator—Green
The Buck/Boost Indicator illuminates when the UPS is operating in Boost mode to compensate for a
low mains voltage condition. This indicator flashes when the UPS is operating in Buck mode to com-
pensate for a high mains voltage condition (see 11.0 - Troubleshooting for details).
6.8 Battery Indicator—Green/Amber
The Battery Indicator illuminates green when the UPS is operating on battery and flashes green
when a low battery condition occurs. The Battery Indicator illuminates amber when a bad battery is
detected, indicating that the batteries need to be replaced (see 11.0 - Troubleshooting for details).
