ELECTRICAL CONNECTIONS
4-WIRE CONNECTION WITH
A POWER SUPPLY CORD
Only a 4-conductor power-supply cord kit rated
120/240 volts, 50 amperes and marked for use
with ranges with closed-loop connectors or open-
end spade lugs with upturned ends shall be used.
The middle (neutral) wire, which is white, of the
power cord or 4-wire conduit has to be connected
to the middle post of the main terminal block.
The other two wires of the power cord or conduit
have to be connected to the outside posts of the
main terminal connection block. The 4th ground
wire (green) must be connected to the frame of
the range with the ground screw.
- Failure to do so can result in electrical shock,
severe personal injury or death.
WARNING
Install the power cord as follows:
For power cord installations, Hook the strain relief over
the power cord hole (1
3
/
8
”) located below the rear of
oven. Insert the power cord through the strain relief and
tighten it. (Refer to Figure 7.)
DO NOT install the power cord without a strain relief.
1. Remove the lower 3 screws from the terminal block
and retain them. (Refer to Figure 9.)
2. Remove ground strap and discard as show in in
Figure 9.
3.
Insert the ground screw into the power cord ground wire
(green) terminal ring and secure it to the range frame.
4.
Insert the 3 screws through each power cord terminal ring
and into the lower terminals of the terminal block. Make sure
that the center (neutral) wire, which is white, is connected to
the center lower position of the terminal block.
5. Tighten 3 screws securely into the terminal block.

Second, install conduit as shown in Figure 6.
For conduit installations, after purchasing a strain relief,
insert it in the conduit hole (1
1
/
8
”). Then install the
conduit through the body of strain relief and fasten the
strain relief with its ring. Reinstall the bracket.
For conduit connections :
If the wire in the conduit is copper it must be 8 or 10
AWG wiring.
If the wire in the conduit is aluminum it must be 6 or 8
AWG wiring.
1. Loosen the lower 3 screws from the terminal block.
Refer to Figure 11.)
2. Insert the bare wire (white/neutral) end through the
center terminal block opening. Do not remove ground
strap connections.
3. Insert the two side bare wire ends into the lower left
and the lower right terminal block opening. Tighten
the 3 screws securely into the terminal block.
