4-wire connection
This appliance must be connected to the power supply
with a listed (UL, CSA, ...) 3-POLE, 4-CONDUCTOR cord
kit rated 125/250 VOLTS, 50 AMPERES DEDICATED
CIRCUIT, and marked for use with ranges. It is the
responsibility of the installer to provide the proper wiring
components (cord, wires, etc.) and complete the electrical
connection as dictated by local codes and ordinances,
and/or the National Electrical Code.
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
lugs attached to the free ends of the individual
conductors, preferably soldered in place.
To wire a 4-wire connection
1. Locate the terminal block on the rear of the unit and
remove cover.
2. Remove upper nuts only from the terminal block
studs. DO NOT remove lower nuts which secure range
internal wiring leads.
3. If applicable, remove the 4-wire power cord from the
appliance.
4. 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.
5. Remove green ground screw and serrated washer
located beneath the terminal block.
6. Secure the neutral, white 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.
