Refer to the unit electrical data for fusesizes. Consult wiring diagram for fi eld connections that mustbe made by the installing (or electrical) contractor.All fi nal electrical connections must be made with a length offlexible conduit to minimize vibration and sound transmissionto the building.General Line Voltage WiringBe sure the available power is the same voltage and phaseshown on the unit serial plate. Line and low voltage wiringmust be done in accordance with local codes or the NationalElectric Code, whichever is applicable.Power ConnectionLine voltage connection is made by connecting the incomingline voltage wires to the “L” side of the contactor as shownin Figures 21a through 21c. Consult Tables 8a through 8c forcorrect fuse size.208-230 Volt OperationVerify transformer tap with air handler wiring diagram toinsure that the transformer tap is set to the correct voltage,208V or 230V.Figure 21a: R-410A Compressor Section Line VoltageField WiringUnit Power Supply(see electrical table for wireand breaker size)ModelCompressor HWGPumpFLAExt LoopPumpFLATotalUnitFLAMinCircuitAmpsMaxFuse/HACRMinAWGMaxWire Ft(m)RLA LRA Qty Crank-case018 7.1 38.0 1 N/A 0.40 4.0 11.5 13.3 20 12 87 (26.6)024 10.3 56.0 1 0.17 0.40 4.0 14.9 17.4 25 10 106 (32.5)030 12.2 67.0 1 0.17 0.40 4.0 16.8 19.8 30 10 93 (28.6)036 13.5 73.0 1 0.17 0.40 4.0 18.1 21.4 30 10 86 (26.4)042 16.5 95.0 1 0.17 0.40 4.0 21.1 25.2 40 10 73 (22.4)048 18.3 109.0 1 0.17 0.40 4.0 22.9 27.4 45 10 67 (20.6)060 25.0 148.0 1 0.29 0.40 4.0 29.7 35.9 60 8 82 (25.1)Rated Voltage of 208-230/60/1 Min/Max Voltage of 197/254HACR circuit breaker in USA only All fuses Class RK-5Wire length based on one way measurement with 2% voltage drop Wire size based on 60°C copper conductor and Minimum Circuit Ampacity.Figure 20: HWG Module Wiring
