CAUTION:
Make sure the AC outlet has been tested for proper grounding. The
outlet should be 117-V AC, 60-Hz, 3-wire (phase, neutral, ground).

below.
!Turn the basic carrier’s power supply switch to the OFF position.
!Turn off the power supply switches on the expansion carriers.
!Unplug the power cords from any auxiliary power units.
!Plug one end of the power cord into the AC INPUT connector
located just below the power switch on the front of the basic
carrier’s power supply.
!Plug the other end of the power cord into the AC outlet, allowing at
least 1 ft. (30.4 cm) of slack in the cord.
!Repeat Steps 4 and 5 for each expansion carrier.
