INTRODUCTION & SYSTEM DESCRIPTION
Congratulations on your choice of the Liebert PowerSure ProActive
Uninterruptible Power System (UPS).  It provides conditioned power to
microcomputers and other sensitive electronic equipment.
The PowerSure ProActive is a compact, “Automatic Voltage Regulation” UPS.  It
offers “line-interactive” features by continuously conditioning and regulating
output voltage, whether the utility power is present or not. It supplies connected
equipment with stepped approximation to sinewave power to simulate the power
generated by the utility.
NOTE:  This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to part 15 of the FCC Rules.  These limits are
designed to provide reasonable protection against harmful interference in a
residential installation.  This equipment uses, generates and can radiate radio
frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference with radio communications.
However, there is no guarantee that interference will not occur in a particular
installation.  If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or more of the
following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and the receiver.
Connect the equipment into an outlet on a circuit different from that which
the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.
BATTERY OPERATION
Battery mode occurs in event of extreme input conditions or complete utility
failure.  During battery mode the Utility LED will flash every second and an alarm
will sound every 3 seconds.  This will change to a beep every second when
battery runs low (approximately 2 minutes remaining).
WARNING:  Turning off the UPS while in battery mode will result in loss of output
power.
Press Battery Test button occasionally to ensure battery is fully charged.
