Any other ordered options.
SAVE THE ORIGINAL SHIPPING CONTAINER
If the UPS needs to be returned to the manufacturer for service, package it in
its original shipping container. If the original container is not available, make
sure that the unit is packed with at least three inches of shock-absorbing
material to prevent shipping damage. Do not use popcorn-type material. Alpha
Technologies is not responsible for damage caused by improper packaging of
returned units.
READ THE OPERATOR'S MANUAL
Become familiar with your UPS front and side panels by reviewing the
drawings and illustrations in this manual before starting installation. If you have
questions regarding safe installation or operation, contact Alpha Technologies.

8.
Slide the new batteries into the UPS until the batteries are sticking out
about 2 inches (5 cm).
9.
Attach the battery cables onto the battery posts of the new batteries.
The red cable should be attached to the positive post and the black
cable to the negative post.
10. Plug in the red/blue battery connector and slide the batteries all the way
in. Reinstall the battery holding bracket and its foam block.
For the Nexsys 900 and 1250:
4.
Undo the two screws on the battery holding bracket and remove the
battery holding bracket and the battery holding foam block.
5.
Pull out the batteries about 2 inches (5 cm) and disconnect the battery
cable connectors. This disconnects the UPS from internal battery
power.
6.
Remove the batteries and the filler foam block from the chassis.
7.
Slide the new batteries into the UPS until the batteries are sticking out
about 2 inches (5 cm).
8.
Attach the battery cable connectors to the battery tabs of the new
batteries. The red cable should be attached to the positive tab and the

9.
Slide the batteries all the way in and position the filler foam block.
10. Reinstall the battery holding bracket and its foam block.
For all models:
11. Close the cover and reinstall the five screws.
12. If the UPS has an external battery pack attached, go to Step 15.
13. Press the Mute and % Batt buttons at the same time for 3 seconds to
exit the Hot Swap mode. The On Line
LED will come on.
14. Press the % Batt button to check the battery capacity.
15. If the UPS is shut off, turn it on and make sure the unit starts. Unplug
the UPS while it is running and check that there is normal AC power at
the output. The UPS output will fail if the batteries have not been
installed correctly. Do not perform this test when running critical loads.
