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). See “AC Outlet Tests,” earlier in this chapter, for instructions.

To prevent someone from accidentally shutting off the power, do not connect the control unit to a switch-controlled outlet. The AC outlet should be within 5 ft. (152 cm) of the control unit.

To connect the control unit to a dedicated AC outlet, follow the steps 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.

! CAUTION:

Do not attach the power cord(s) to any building surfaces.
