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.
