Installation Manual Power Cord Connections 4-Wire Connection instructions Before wiring the range, review the suggested power source location drawing in Figure 2. If connecting to a 4-wire electrical system for a new branch-circuit or mobile home use a 4-wire connection. 1 Follow the power supply cord kit manufacturer's Installation Instructions and install the strain relief clamp on the cord. See Figure 8. 2 Connect the end connectors for line 1, line 2 and neutral and tighten securely to the terminal block. See Figure 9. IMPORTANT DO NOT LOOSEN the factory installed nut connections which secure the range wiring to the terminal block. Electrical failure or loss of electrical connection may occur if these 3 nuts are loosened or removed. 3 You must disconnect the ground strap. Remove the factory installed ground screw and plate to release the copper ground strap from the frame of the range. Cut and discard the copper ground strap and plate. KEEP the ground screw. See Figure 9. 4 Connect the green ground wire lead with the eyelet to the frame of the range with the ground screw using the same hole in the frame where the ground screw was originally installed. See Figure 9. 5 Make sure all screws are tightened securely and replace the rear access cover and secure with screw. See Figure 7. 3-Wire Connection Instructions For existing installations ONLY, refer to Figure 10. 1 Follow the power supply cord kit manufacturer's Installation Instructions and install the strain relief clamp. See Figure 10. 2 Connect the end connectors for line 1, line 2 and neutral and tighten securely to the terminal block. See Figure 10. IMPORTANT DO NOT LOOSEN the factory installed nut connections which secure the range wiring to the terminal block. Electrical failure or loss of electrical connection may occur if these 3 nuts are loosened or removed. 3 A ground strap is installed on this range which connects the center terminal of the neutral terminal block to the range chassis. The ground strap is connected to the range by the center, lowest screw. See Figure 10. The ground strap must not be removed unless National, State or Local Codes do not permit use of a ground strap. NOTE: If the ground strap is removed for any reason, a separate ground wire must be connected to the separate ground screw attached to the range chassis and to an adequate ground source. 4 Make sure all connections are tightened securely and replace the rear access cover and secure with screw. See Figure 7. 3 & 4-WIRE PERMANENT WIRE CONNECTIONS 3-wire permanent connection - follow steps 1, 2 and 5 below. 4-wire permanent connection - follow all steps below. Before wiring the range, review the suggested power source location drawings in Figure 2. If connecting to a 4-wire electrical system: 1 Follow the manufacturer's Installation Instructions for installing the strain relief clamp. 2 Strip insulation away from the ends of the permanent wiring for line 1, line 2 and neutral; also strip ground wire on 4-wire connections. Tighten all 3 or 4-wire leads to the terminal block. Follow wire locations shown in Figure 11. IMPORTANT DO NOT LOOSEN the factory installed nut connections which secure the range wiring to the terminal block. Electrical failure or loss of electrical connection may occur if these 3 nuts are loosened or removed. NOTE: For 3-wire permanent connection skip steps 3 and 4 and continue with step 5. 3 Disconnect the ground strap. Remove the factory installed ground screw and plate to release the factory installed copper ground strap from frame of the range. Cut and discard the copper strap from the terminal block. KEEP the ground screw, ground plate and go to step 4. 4 Connect the green ground wire lead to the frame of the range using the ground screw and plate as shown in Figure 12. Be sure to install using the same hole in the frame where the ground screw was originally installed. 5 Make sure all connections are tightened securely and replace the rear access cover. See Figure 7. NOTE: Non-terminated field wire compression connections must be set at approximately 90 in./lb. 4-Wire Connection Connect line 1 here. Cut ground strap. Discard ground strap and ground plate. lack Connect green en insulated copper ground wire with ground screw here. Figure 9 red white gre b Note: Install strain relief clamp. Center or white wire must always be attached to the center terminal on block. Terminal block Connect line 2 here. Connect neutral (white or center) here. A user supplied strain relief clamp must be installed at this location. It requires 1 3/8" (3.5 cm) diameter cord kit hole. 3-Wire Connection Connect line 1 here. Ground strap Note: Install strain relief clamp. Center must always be attached to the center terminal on block. Figure 10  Terminal block Connect line 2 here. Connect neutral here. A user supplied strain relief clamp must be installed at this location. It requires 1 3/8" (3.5 cm) diameter cord kit hole.
