26.
Reinstall the battery fuse and cap.
27.
Next temporally connect one end of a 100 ohm, 10 watt resistor to the - (black)
terminal of BATT 6. Next, touch the metal fast-on terminal connected to the black
(-15) the other end of the resistor for 30 seconds. Next, remove the resistor and
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.
40.
Reinstall the two screws on the right side of the UPS top cover.
Testing the UPS
1.
Depress the “on” button located on the UPS front panel. The UPS should cold start
and operate normally in battery mode.
2.
Depress the “on” button again and the UPS should shutdown after several seconds.
3.
Connect the UPS to an utility power source.
4.
Turn on the UPS power switch located on the rear panel. The UPS should power up
and function normally as defined in the Owner’s Manual.
5.
Leave the UPS turned on for 24 hours to allow the batteries to fully charge.
