AC Power and Grounding

Proper power and grounding are essential for the system to run correctly and safely.

! CAUTION:

If any of the following requirements are not met, the customer must contact a licensed electrician. Do not install the system until all requirements are met.

Verify that all of the following power and grounding requirements are met:

■The load center of appropriate current rating must be equipped with circuit breaker(s) labeled 120 V AC, 15 amps.

■Each breaker must protect one dedicated quad AC outlet or two dedicated duplex AC outlets.

■All AC outlets must connect to the same load center and the ground wire must connect to the single-point ground bar on the first AC outlet (see Figure 2–1).

■One outlet must have an attached ground bar connected by a #6 AWG copper wire to an approved ground (see “Approved Grounds,” later in this chapter, for a description of approved grounds). This ground bar is the system’s single-point ground (see Figure 2–1).

■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.

■Each carrier requires one AC outlet receptacle.

■Auxiliary equipment requires additional AC outlets.

■If a printer or PC is installed on the system, it must be plugged into the same AC branch as the power supply of the basic carrier.
