To wire a 4-wire connection 1. Locate the terminal block on the rear of the unit and remove cover. 2. Remove upper nuts only from the terminal block studs. DO NOT remove lower nuts which secure range internal wiring leads. 3. If applicable, remove the 4-wire power cord from the appliance. 4. Mount strain relief (not provided with range) into the 1'' (25.4 mm) diameter hole in the back panel located below the terminal block. Route wires up through strain relief. 5. Remove green ground screw and serrated washer located beneath the terminal block. 6. Secure the neutral, grounded wire of the supply circuit, to the center stud of the terminal block with nut. 7. Secure the L1 (red) and L2 (black) power leads to the outside terminal studs (brass colored) with nuts. 8. Secure the bare copper ground lead to the range chassis using the ground screw and serrated washer. Be sure that neutral and ground terminals do not touch. 9. Tighten all connections securely and 10. Reinstall the terminal block cover. 3-wire lead connection Where local codes and ordinances permit grounding through neutral, and conversion of supply to 4-wire is impractical, the unit may be connected to the power supply with a Listed (UL, CSA, ...) 3-POLE, 3CONDUCTOR cord kit rated 125/250 VOLTS, 50 AMPERES DEDICATED CIRCUIT, and marked for use with ranges. It is the responsibility of the installer to provide the proper wiring components (cord, wires, etc.) and complete the electrical connection as dictated by local codes and ordinances, and/or the National Electrical Code. The cord kit must be attached to the range back panel with a strain relief which will fit a 1" (25.4 mm) diameter hole. If not already equipped, the cord must also have 1/4'' (6 mm) faston closed-loop lugs attached to the free ends of the individual conductors, preferably soldered in place. To wire a 3-wire connection 1. Locate the small bag with white jumper wire located in the literature packet. 2. Locate the terminal block on the rear of the unit and remove cover. 3. Remove upper nuts only from the terminal block studs. DO NOT remove nuts which secure range internal wiring leads. 4. If applicable, remove the 4-wire power cord from the appliance. 5. Mount strain relief (not provided with range) into the 1'' (25.4 mm) diameter hole in the back panel located below the terminal block. Route wires up through strain relief. d c a b a - Red/L1 c - White/neutral b - Green/ground d - Black/L2 Page. 18

3-wire lead connection
Where local codes and ordinances permit grounding
through neutral, and conversion of supply to 4-wire is
impractical, the unit may be connected to the power
supply with a Listed (UL, CSA, ...) 3-POLE, 3-
CONDUCTOR cord kit rated 125/250 VOLTS, 50
AMPERES DEDICATED CIRCUIT, and marked for use with
ranges. It is the responsibility of the installer to provide
the proper wiring components (cord, wires, etc.) and
complete the electrical connection as dictated by local
codes and ordinances, and/or the National Electrical
Code.
The cord kit must be attached to the range back panel
with a strain relief which will fit a 1" (25.4 mm) diameter
hole. If not already equipped, the cord must also have
