3 Make sure all connections are tightened securely and replace the rear access cover. See Figure 7. GROUNDING INSTRUCTIONS- ONLY 3-WIRE CONNECTIONS: 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 9. 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. 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 manufacturerʼs Installation Instructions supplied with the strain relief clamp and install. 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 4-WIRE CONNECTION INSTALLATION MANUAL connections. Tighten all 3 or 4-wire leads to the terminal block. Follow wire locations shown in 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. 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 11. 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./lbs. FOR 3 & 4-WIRE PERMANENT CONNECTIONS Connect line 1 here. Cut ground strap.
