Basic Operation
This setting is normally set to 100%, which enables the UPS to protect against waveform distortions in its AC input. When such distortion occurs,
the UPS will normally switch to providing PWM sine wave power from its battery reserves for as long as the distortion is present. In some areas with
poor utility power or where the UPS’s input power comes from a backup generator, frequent brownouts and/or chronic waveform distortion could
cause the UPS to switch to battery too often, draining its battery reserves. You may be able to reduce how often your UPS switches to battery due
to waveform distortion or brownouts by experimenting with different settings. As the setting is reduced, the UPS becomes more tolerant of
variations in its input power’s AC waveform.
Note:
When experimenting with different settings, operate connected equipment in a safe test mode so that the effect on the equipment of any waveform distortions
in the UPS’s output can be evaluated without disrupting critical operations. The experiment should last long enough to assure that all expected line conditions are
encountered.

Press the
MUTE
button to advance to the next available option. The last option displayed, before navigating away from this menu option, will be the
selected setting.
This display option allows the user to select the option to automatically scroll each operating condition of the UPS (such as Input Voltage, Output
Voltage and Runtime) automatically.
Notes:
1. Each condition is displayed in 2 second intervals.
2. If a button is pressed while Scroll Mode is enabled, the scroll function will pause for 10 seconds to allow the user to manually make menu selections.
External Battery Setting Control (XL model only)
Tap the
MODE
button repeatedly to advance to the External Battery screen, as shown here:
Press the
MUTE
button to advance to the next available option. The last option displayed, before navigating away from this menu option, will be the
selected setting.
Note:
The Battery Runtime calculation is based on this setting.
This feature setting allows the user to configure the UPS for use with an External Battery Pack or without an External Battery Pack. The Runtime will
be automatically reconfigured.
Note:
Battery Packs cannot be daisychained. Only one Battery Pack can be attached to the UPS.
Error Messages
In the event the UPS battery requires replacement, the
icon will flash, as well as the icon. If there is an overload, the
, , and
icons will flash simultaneously along with a numeric read out of the load percentage.
