Installation (Continued)
2. If the unit is not equipped with an optional factory in-
stalled non-fused disconnect switch, a field supplied dis-
connect switch must be installed at or near the unit in ac-
cordance with the National Electrical Code (NEC latest
edition). Refer to the "Power Wire Sizing & Protection De-
vice Equations" (DSS calculation), for determining the
correct size.
3. Location for the electrical service entrance is illustrated in
Figure 3-2. Complete the unit's power wiring connections
onto either the main terminal block 1TB1, or the factory
mounted non-fused disconnect switch 1S14, inside the
unit control panel. Refer to the customer connection dia-
gram that shipped with the unit for specific termination
points.
4. Provide proper grounding for the unit in accordance with
local and national codes.
