4-wire connection
This appliance must be connected to the power supply
with a listed (UL, CSA, ...) 3-POLE, 4-CONDUCTOR cord

The cord kit is required to be attached to the range
terminal block with a strain relief (not provided) 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

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.
