See Convenience Outlets on page 18 for pow-er transformer connections.The field power wires are connected to the unit at line-sidepressure lugs on compressor contactor C and indoor fan con-tactor IFC (see wiring diagram label for control box compo-nent arrangement) or at factory-installed option non-fused dis-connect switch or HACR. Maximum wire size is #2ga AWG(copper only) per pole on contactors and #2ga AWG (copperonly) per pole on optional disconnect or HACR. See Fig. 26and unit label diagram for field power wiring connections.NOTE: Unit may be equipped with short test leads (pigtails) onthe field line connection points on contactor C or optional discon-nect switch. These leads are for factory-run test purposes only; re-move and discard before connecting field power wires to unit con-nection points. Make field power connections directly to line con-nection pressure lugs only.Fig. 26 — Power Wiring ConnectionsFig. 27 — Disconnect Switch and UnitUNITS WITH FACTORY-INSTALLED NON-FUSED DIS-CONNECT OR HACRThe factory-installed option non-fused disconnect (NFD) orHACR switch is located in a weatherproof enclosure locatedunder the main control box.
