IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
This guide contains important instructions which must be followed during the maintenance of
this UPS and its batteries. Please read all instructions before operating this equipment and
save this guide for future reference.
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.
High voltage exists within the unit, which could cause electrical shock. Always unplug
this UPS and remove the UPS battery fuse (if present) prior to attempting battery
replacement.
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.
This UPS contains sealed maintenance-free batteries (VRLA). When situated in a
typical office environment, with the proper charging and limited cycling, the batteries
can last many years. In home, office or computer room environments, the batteries
should be replaced every three to five years. In critical applications replace the
batteries every two years.
When replacing the UPS batteries, use the same number and type of batteries. The
batteries approved for the Falcon SG1K-1T & SG1K-2T models are as follows:
6 pieces of Yuasa/Enersys NP7-12, 7Amp Hour, 12Vdc VRLA Type Battery
or
6 pieces of CSB GP 1272 F2, 7.2 Amp Hour, 12Vdc VRLA Type Battery
NEVER dispose of batteries in a fire, as batteries will explode.
NEVER dispose of used batteries in the trash or landfill as it is a violation of federal
and state laws. The batteries must be recycled.
For battery recycling information, please contact:

7. Remove the four screws securing the left side of the upper and lower battery hold-
down brackets to the lower chassis.
8. Gently lift the battery hold down bracket and rotate it off of the batteries. Use care
not to pull the remaining wiring connected to the battery hold down bracket.
9. Remove the red wire (+15), battery fast-on terminal from the + (red) side of BATT1
as shown.
10. Remove the black wire (-15), battery fast-on terminal from the - (black) side of
BATT6 as shown.
11. Remove the black jumper from BATT1 - (black) and BATT2 + (red).
12. Remove the black jumper from BATT2 - (black) and BATT3 + (red).
13. Remove the black jumper from BATT3 - (black) and BATT4 + (red).
14 Remove the black jumper from BATT4 - (black) and BATT5 + (red).
15. Remove the black jumper from BATT5 - (black) and BATT6 + (red).
16. Note the position of the six batteries and remove them from the chassis. See the
battery connection diagram below.
WHEN REMOVING AND INSTALLING THE NEW BATTERIES, EXTREME CARE MUST
BE USED NOT TO SHORT METAL CHASSIS PARTS ACROSS THE BATTERY
TERMINALS AND NOT TO SHORT THE BATTERIES TO EACH OTHER OR
PERSONAL INJURY MAY RESULT.
17. Reinstall six new batteries in the same placement as the six just removed.

18. Verify the UPS chassis orientation has not moved since reinstalling the batteries.
19. Reconnect the Red (+15) wire to the + (red) terminal on BATT 1 as shown.
20. Reconnect one end of the 1st Black jumper wire to the - (black) terminal of BATT 1
and reconnect the second end of the 1st jumper to the + (red) terminal of BATT 2
as shown.
21. Reconnect one end of the 2nd Black jumper wire to the - (black) terminal of BATT 2
and reconnect the second end of the 2nd jumper to the + (red) terminal of BATT 3
as shown above.
22. Reconnect one end of the 3rd Black jumper wire to the - (black) terminal of BATT 3
and reconnect the second end of the 3rd jumper to the + (red) terminal of BATT 4
as shown above. CAUTION: Move this jumper wire to under the sheet metal lip to
prevent the top cover from shorting the jumper when reinstalled.
23. Reconnect one end of the 4th Black jumper wire to the - (black) terminal of BATT 4
and reconnect the second end of the 4th jumper to the + (red) terminal of BATT 5
as shown above.
24. Reconnect one end of the 5th Black jumper wire to the - (black) terminal of BATT 5

should read +72-81Vdc if the batteries are connected correctly. If the voltage
reading is 0Vdc, less than 65Vdc. check all battery wiring connections This voltage
must read +72-81Vdc before performing the next step.

reconnect the Black 15- wire to the - (black) terminal of BATT 1 as shown on the
previous page. This is necessary to precharge the UPS electronics.
29. Recheck all battery connections to make sure the fast-on terminals are all the way on
the battery terminals and that they are tight.
30. Dress the battery wiring between and around the batteries so that the wires will not
be pinched between the battery hold down bracket when reinstalled. Also check to
make sure that no wiring can be pinched or shorted to the battery terminals.
32. Carefully reinstall the battery hold down brackets back up over the batteries, carefully
sliding the right side of the brackets under the hold down screws.
33. Reinstall the four screws securing the left side of the two battery old down brackets
and tighten.
34. Tighten the four screws securing the right side of the two battery hold down brackets.
35. Perform a last visual inspection. Check all wiring and connections. Make sure no
wiring will be pinched or shorted when the UPS top cover is reinstalled.
36. Set the UPS in an upright position.
37. Position the top cover so the open side slides over the rear of the UPS and continue
to slide it forward until the front of the top cover is flush with the UPS front plastic
bezel. Verify no wiring has been pinched. Use care not to short the top cover to the
internal UPS electronics.
38. Reinstall the four rear panel screws removed in step 2 and tighten.
39. Reinstall the two screws on the right side of the UPS top cover.
