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) device

WARNING
Proper Field Wiring and Grounding
Required!
Failure to follow code could result in death or serious
injury.
All field wiring MUST be performed by qualified
personnel. Improperly installed and grounded field
wiring poses FIRE and ELECTROCUTION hazards. To
avoid these hazards, you MUST follow requirements
for field wiring installation and grounding as
described in NEC and your local/state/national
electrical codes.
The location of the electrical service entrance is illustrated
in
Figure 16, p.
37. It is 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 diagrams that shipped with the unit for specific
termination points.
Provide proper grounding for the unit in accordance with
local and national codes.
