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.

Installation (Continued)

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.
