Main Unit Power Wiring
Table 10, p. 37 lists the field connection wire ranges for
both the main power terminal block 2XD1 and the
optional main power disconnect switch 2QB1. Service
Sizing Data lists the component electrical data.
The electrical service must be protected from over
current and short circuit conditions in accordance with
NEC requirements. Protection devices must be sized
according to the electrical data on the nameplate. Refer
to the equations listed in the product catalog to
determine the following:
• the appropriate electrical service wire size based on
“Minimum Circuit Ampacity” (MCA)
• the “Maximum Over Current Protection” (MOP)

The location of the electrical service entrance is
illustrated in Figure 16, p. 37. It’s important to complete
the unit power wiring connections onto either the main
terminal block or the factory mounted, non-fused
disconnect switch. The disconnect switch is inside the
unit power box. Refer to the component location
diagrams that shipped with the unit for specific
termination points.
Provide proper grounding for the unit in accordance
with local and national codes.
