ELECTRICAL CONNECTIONSELECTRICAL SHOCK HAZARDFailure to follow this warning could result in personalinjury or death.Blower access panel door switch opens 115-v powerto control. No component operation can occur. Do notbypass or close switch with panel removed.See Figure 26 for field wiring diagram showing typical field115-v wiring. Check all factory and field electricalconnections for tightness.ELECTRICAL SHOCK AND FIRE HAZARDFailure to follow this warning could result in personalinjury, death, or property damage.The cabinet MUST have an uninterrupted orunbroken ground according to NEC ANSI/NFPA70-2008 or local codes to minimize personal injury ifan electrical fault should occur. This may consist ofelectrical wire, conduit approved for electrical groundor a listed, grounded power cord (where permittedby local code) when installed in accordance withexisting electrical codes. Refer to the power cordmanufacturer's ratings for proper wire gauge. Do notuse gas piping as an electrical ground.FURNACE MAY NOT OPERATEFailure to follow this caution may result in intermittentfurnace operation.Furnace control must be grounded for properoperation or else control will lock out. Control mustremain grounded through green/yellow wire routed togas valve and manifold bracket screw.115-V WIRINGVerify that the voltage, frequency, and phase correspond tothat specified on unit rating plate. Also, check to be sure thatservice provided by utility is sufficient to handle load imposedby this equipment. Refer to rating plate or Table 7 forequipment electrical specifications.Make all electrical connections in accordance with NationalElectrical Code (NEC) ANSI/NFPA 70-2008 and any localcodes or ordinances that might apply.FIRE HAZARDFailure to follow this warning could result in personalinjury, death, or property damage.Do not connect aluminum wire between disconnectswitch and furnace. Use only copper wire.Use a separate, fused branch electrical circuit with a properlysized fuse or circuit breaker for this furnace. See Table 7 forwire size and fuse specifications. A readily accessible meansof electrical disconnect must be located within sight of thefurnace.NOTE: Proper polarity must be maintained for 115-v wiring.If polarity is incorrect, control LED status indicator light willflash a status code 10 and furnace wilt NOT operate.J-BOX RELOCATIONNOTE: If factory location of J-Box is acceptable, go to nextsection (ELECTRICAL CONNECTION TO J-BOX).NOTE: On 14-in. (356 mm) wide casing models, the J-Boxshall not be relocated to other side of furnace casing whenthe vent pipe is routed within the casing.1. Remove and save two screws holding J-Box. (SeeFigure 23)NOTE: The J-Box cover need not be removed from theJ-Box in order to move the J-Box. Do NOT remove greenground screw inside J-Box. The ground screw is notthreaded into the casing flange and can be lifted out of theclearance hole in casing while swinging the front edge of theJ-Box outboard of the casing.2. Cut wire tie on loop in furnace wires attached to J-box.3. Move J-Box to desired location.4. Fasten J-Box to casing with two screws removed inStep 1.5. Route J-Box wires within furnace away from sharpedges, rotating parts and hot surfaces.ELECTRICAL CONNECTION TO J-BOXField-Supplied Electrical Box on Furnace J-Box Bracket SeeFigure 24.1. Remove cover from furnace J-Box.2. Attach electrical box to furnace J-Box bracket with atleast two field-supplied screws through holes in elec-trical box into holes in bracket. Use blunt-nose screwsthat will not pierce wire insulation.3. Route furnace power wires through holes in electricalbox and J-Box bracket, and make field-wire connec-tions in electrical box. Use best practices (NEC in U.S.)for wire bushings, strain relief, etc.4. Route and secure field ground wire to green groundscrew on J-Box bracket.5. Connect line voltage leads as shown in Figure 26.6. Reinstall cover to J-Box. Do not pinch wires betweencover and bracket. Electrical Box on Furnace CasingSide See Figure 24.FIRE OR ELECTRICAL SHOCK HAZARDFailure to follow this warning could result in personalinjury, death, or property damage.If field-supplied manual disconnect switch is to bemounted on furnace casing side, select a locationwhere a drill or fastener cannot damage electrical orgas components.1. Select and remove a hole knockout in the caslngwhere the electrical box is to be installed.NOTE: Check that duct on side of furnace will not interferewith installed electrical box.2. Remove the desired electrical box hole knockout andposition the hole in the electrical box over the hole inthe furnace casing.3. Fasten the electrical box to casing by driving two fieldsupplied screws from inside electrical box into casingsteel.20 441 01 1402 02 |
