IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
This manual contains important instructions which must be followed during the installation,
operation and maintenance of this UPS and its batteries. Please read all instructions before
operating this equipment and save this manual for future reference.
All of the models presented herein are designed for installation and use in a protected, temperature controlled
environment, free of contamination.
This UPS utilizes voltage that may be hazardous. Do not attempt to disassemble. This unit contains no user
replaceable parts. Refer all servicing to Falcon Electric, Inc.
THIS UPS IS NOT INTENDED TO BE USED IN CONJUNCTION WITH LIFE SUPPORT OR OPERATING
ROOM EQUIPMENT.
Always unplug this UPS and remove the UPS battery fuse prior to cleaning and never apply liquid or spray
detergent on the UPS.
Never attempt to service batteries. High voltage exists within the unit, which could cause electrical shock.
Servicing of batteries should be performed or supervised by personnel knowledgeable of batteries and the
required precautions. Keep unauthorized personnel away from batteries. When replacing the UPS batteries,
use the same number and type of batteries.
Allow at least 24 hours, after the UPS is first installed and turned on, to fully charge the internal battery and
assure the maximum backup time is available.
DO NOT plug this UPS into its own output as this may damage the UPS. NEVER CONNECT equipment that
could overload the UPS or demand half-wave rectification from the UPS, for example: electric drills, vacuum
cleaners or hair dryers. Never connect surge protected plug strips to the UPS output.
DO NOT remove or unplug the input cord when the UPS is turned on. This removes the safety ground from
the UPS and the equipment connected to the UPS.
This UPS contains its own energy source (batteries). The output receptacles may carry live voltage
even when the UPS is not connected
to an AC source.
Should any SG Series UPS units be stored for more than two weeks, it is mandatory that the
battery
fuse be removed prior to storage or battery
damage will result.

SG Series UPS - Overview
General - Common for all models
1. Verify the following is included in the UPS shipping carton:
(1) UPS, (1) Software Diskette(s) & Manual, (1) Owners Manual & (1) UPS/Computer
Cable.
2. Verify the UPS unit is configured for the proper input/output voltage and frequency. This
information is stated on the nameplate label located on the rear or the side panel of the
unit. If any special input plug and output receptacle configurations were specified at the
time of order, verify for proper configuration.
3. Set the output voltage and green mode switches located on the UPS rear panel for the
nominal UPS output voltage desired. See the switch setting tables located on
page 5.
In most cases the nominal UPS output voltage should be set to match the incoming utility
voltage. This will assure a close matching voltage in the event the UPS is placed on
bypass. NOTE: Disregard the "ON" marking on the side of the actual dip switch
housing; use the tables in this manual or the silkscreen on the UPS rear panel only.
Dip switch 3 "enables" or "disables” the "Green Mode" function. The UPS is shipped
from the factory with the switch set in the "disabled" position (up). If SW3 is switched
down or to the "enabled" position, the Green Mode function is activated. When the
load connected to the output of the UPS drops to under 10% of the full rated UPS output
for 30 seconds, the UPS is automatically placed into bypass and the inverter is turned off.
NO BATTERY BACKUP IS PROVIDED AFTER THE GREEN MODE HAS ACTIVATED.
Dip switch settings must be made while the UPS is turned off. Any changes made while
the UPS is turned on will not take effect until the UPS is turn off and back on again since
the switch settings are read by the microprocessor only during initial UPS power up
.
4. To prevent accelerated battery discharge during shipment, this UPS was shipped with the
battery circuit breaker turned off. TURN THE BATTERY DISCONNECT CIRCUIT
BREAKER ON PRIOR TO TURNING ON THE UPS INPUT CIRCUIT BREAKER.
NEVER TURN THE BATTERY CIRCUIT BREAKER OFF WHILE THE UPS AC CIRCUIT
BREAKER IS TURNED ON AND OPERATING FROM THE UTILITY VOLTAGE, OR UPS
DAMAGE MAY RESULT. UPS MUST BE COMPLETELY SHUT DOWN PRIOR TO
DISABLING THE INTERNAL BATTERY SUPPLY.
In the event this UPS is to be turned off or stored for more than two weeks, the battery
circuit breaker must be turned to the off position to prevent battery discharge. If placed in
long-term storage, every four months the UPS must be plugged in and turned on for 24
hours to allow the batteries to recharge and prevent battery damage. Failure to follow
these procedures will invalidate your warranty.

5. Select a suitable location for the UPS.
VERIFY THE FLOOR OR SURFACE SUPPORTING THE UPS WILL SUPPORT THE
WEIGHT OF THE UPS AND ANY OPTIONAL EXTENDED BATTERY BANKS.
SG2K-2T-HW & SG2K-2T-HW UPS MODELS = 68.4 lbs. (31 kg)
SG3K-2T-HW & SG3K-2-HW UPS MODELS = 81.4 lbs. (37 kg)
6. If unattended computer shutdown and monitoring are desired, connect the green
UPS/Computer cable to the DB-9 connector located on the UPS rear panel. Then
install the shutdown and monitoring software provided with the UPS. For your
reference, UNIX shutdown and monitoring software is available from Falcon Electric
at an additional cost.
7. Verify the location selected has adequate ventilation to allow for the proper cooling of
the UPS.
DO NOT BLOCK UPS FANS OR AIR VENTS. THE UPS MUST NOT BE
INSTALLED IN AN ENCLOSED AREA.

1.0 UPS Input & Output Requirements.
Note: All SG Series hardwire UPS models must be installed by a licensed
electrician, in accordance with the National Electrical Code (NEC) ANSI/NFPA70
and all local regulations. It is further required that the input of SG Series hardwire
UPS be wired to a building service panel incorporating a dedicated “branch
rated” circuit breaker of the proper rating.
