Preparation

Power and Grounding

Proper power and grounding are essential for correct and safe
functioning of the system.
Power Requirements
The customer should provide a load center of appropriate
current rating equipped with 120-VAC, 15-amp circuit breaker(s).
Each breaker must protect one dedicated quad AC outlet or two
dedicated duplex AC outlets.
One outlet must have an attached ground bar connected by a
#6 AWG copper wire to an approved ground. This ground bar is
the system's single-point ground (see Figure 11).
Table 2-5 contains the AC power requirements and specifica-
tions for the CU.
