Remove front panel. Connect the AC input and
re-connect battery wires. Put the front panel back to the
unit.
Step 2: UPS input connection
Plug the UPS into a two-pole, three-wire, grounded receptacle only. Avoid using extension
cords.

For 200/208/220/230/240VAC models: The power cord is supplied in the UPS package.

For 100/110/115/120/127VAC models: The power cord is attached to the UPS. The input
plug is a NEMA 5-15P for 1K and 1K-L models, NEMA 5-20P for 2K and 2K-L models.
Note: For Low voltage models : Check if the site wiring fault indicator lights up in LCD panel. It
