4-CONDUCTOR CORD -- 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 which will fit a 1" (25.4mm) diameter
hole. If not already equipped, the cord must also have 1/4"
(6mm) faston closed-loop lugs attached to the free ends of
the individual conductors, preferably soldered in place.
4-Wire Connection
1. Remove upper nuts only from the terminal block studs.
Do not remove lower nuts which secure range internal
wiring leads.
2. Mount strain relief (not provided with range) into the 1"
(25.4mm) diameter hole in the back panel located
below the terminal block (see Figure 12). Route wires
up through strain relief.
3. Secure the neutral, grounded wire of the supply circuit,
to the center stud of the terminal block with nut (see
Figure 13).
4. Secure the L1 (black) and L2 (red) power leads to the
outside terminal studs (brass colored) with nuts.
5. Remove green ground screw located beneath the
terminal block. Discard white wire.
6.
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.
7. Tighten all connections securely.
3-CONDUCTOR CORD -- WHERE LOCAL CODES AND
ORDINANCES PERMIT GROUNDING THROUGH
NEUTRAL, AND CONVERSION OF SUPPLY TO 4 WIRE
IS IMPRACTICAL, UNIT MAY BE CONNECTED TO THE
POWER SUPPLY WITH A 3-POLE, 3-CONDUCTOR
CORD KIT RATED 125/250 VOLTS, 50 AMPERES, AND
MARKED FOR USE WITH RANGES.

3. Secure the neutral, grounded wire of the supply circuit,
to the center stud (silver colored) of the terminal block
(see Figure 14).
4. Secure the L1 (black) and L2 (red) power leads to the
outside corresponding terminal block studs (brass
colored).
5. Secure one end of the mounted looped neutral wire,
located beneath terminal block, to the center stud of
