Place the two EU2000AI generators side by side with the outlets facing you. Locate the two parallel 1/4-jack ports on the upper left-hand corner of the outlet panel marked "parallel operation."
Plug the two red jacks from the parallel connection kit into the first generator. Remove the screw from the bottom left of the outlet station, below the parallel ports, with a Phillips head screwdriver. Place the black ground lead from the parallel connection kit over the screw hole. Reinstall the screw and tighten it down with the screwdriver.
