4-Wire Connection
Normally, 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 11).
2. Remove upper nuts only from the terminal block studs.
Do not remove lower nuts which secure range internal
wiring leads.
3. 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.

Figure 12).
5. Secure the LI (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.
