4-Wire Connection

A unit must be connected to the power supply with a 3-

POLE, 4-CONDUCTOR cord kit rated 125/250 VOLTS, 50

AMPERES, and marked for use with ranges.

The cord kit must 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 lugs

attached to the free ends of the individual conductors,

preferably soldered in place.

1. Locate the terminal block on the rear of the unit and

remove cover (see Figure 16).

2. 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.

3. Remove upper nuts only from the terminal block studs.

Do not remove lower nuts which secure range internal

wiring leads.

4. Secure the neutral, grounded wire of the supply circuit,

to the center stud of the terminal block with nut (see

Figure 17).

5. Secure the L1 (red) and L2 (black) power leads to the

outside terminal studs (brass colored) with nuts.

6. Remove green ground screw located beneath the

terminal block. Discard white wire.

7. Secure the bare copper ground lead to the range

chassis using the ground screw previously used for the

white wire. Be sure that neutral and ground terminals

do not touch.

8. Tighten all connections securely.

9. Reinstall the terminal block cover.

INSTALLER — show the owner the location of the circuit

breaker. Mark it for easy reference.
