ing requirements.
WARNING
An improper 240/208 VAC power supply will cause mal-
function, damage to this appliance, and possibly create a
condition of shock hazard.
This appliance must be properly grounded.
Before installing, turn power OFF at the service panel.
Lock service panel to prevent power from being turned
▶
ON accidentally.
Prior to servicing the appliance, always disconnect the
¡
appliance's electrical supply cord, if so equipped, from
the wall receptacle. If the appliance is hard-wired to the
power supply, disconnect the power to appliance by
turning off the proper circuit breaker. Lock the service
panel to prevent the power from being turned ON acci-
dentally.
A neutral supply wire must be provided from the power
¡
source (breaker) because critical range components re-
quire it to operate safely and properly.
Mount the receptacle securely to a wall stud, then seal
¡
around the receptacle's housing.
If the correct power supply circuit is not provided, it is
¡
the responsibility and obligation of the installer and user
to have a proper power supply connected. This must be

6.2 Preparation for power connection
WARNING
Risk of Electric Shock or Fire. Grounding through the neu-
tral conductor is prohibited for new branch-circuit installa-
tions (1996 NEC), mobile homes, and recreational vehi-
cles, or in an area where local codes prohibit grounding
through the neutral conductor.
Where grounding through the neutral conductor is
prohibited:
Disconnect the link from the neutral.
¡
Use grounding terminal or lead to ground unit.
¡
Connect neutral terminal to lead branch circuit neutral in
¡
the usual manner. When the appliance is to be con-
nected by means of a cord kit, use a 4-conductor cord
for this purpose.
cal codes. In the absence of local codes and ordi-
nances, the power supply connection shall be in accor-
dance with the National Electrical Code.
Observe all governing codes and ordinances when
¡
grounding. In the absence of these codes or ordinances
observe National Electrical Code ANSI/ NFPA 70 cur-
rent issue. See the following information in this section
for grounding method.
Electrical wiring diagrams and schematics have been
¡
placed in the toe kick panel area of the range for access
by a qualified service technician. → Page 13
The ranges are to be connected to a 240/208 VAC
¡
power supply.
The range must be connected to the power supply utiliz-
¡
ing one of the following methods. For all methods of
connection, the length of the cord or conduit/wiring must
allow the appliance to be slid completely out of the cabi-
net without having to unplug or disconnect the appli-
ance from the power supply.
The recommended minimum free length of cord or con-
¡
duit is 4 ft (1.2 m). Electrical installations and grounding
must be in accordance with all local codes and ordi-
nances, and/or the National Electrical Code, as applica-
ble.
When using a receptacle it may be necessary to recess
¡
the receptacle's housing into the rear wall. Refer to Lo-
cal Electrical Code to determine the minimum volume
for all electrical / junction boxes. Follow all local electri-
cal codes and ordinances, and/or the National Electrical
Code, as applicable.

Requirements
This appliance must be connected to the power supply
¡
with a listed (UL, CSA, ...) 3-POLE, 4-CONDUCTOR
cord kit rated 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 com-
plete the electrical connection as dictated by local
codes and ordinances, and/or the National Electrical

The cord kit is required to be attached to the range ter-
¡
minal block with a strain relief which will fit a
1" (25.4 mm) diameter hole.
If not already equipped, the cord must also have
¡
¼" (6 mm) faston closed-loop lugs attached to the free
ends of the individual conductors, preferably soldered in
place.
Disconnect the electrical power at the breaker box.
