SECTION 2 - INSTALLATION

VIII. ELECTRICAL SUPPLY (all ovens)

 

WARNING

 

Authorized supplier personnel normally accomplish

 

the connections for the ventilation system, electric supply,

ENGLISH

and gas supply, as arranged by the customer. Following these

connections, the factory-authorized installer can perform the

Canadian Electrical Code, CSA C22.2; the Australian Code

 

initial startup of the oven.

 

NOTE: The electric supply installation must satisfy the

 

requirements of the appropriate statutory authority, such as the

 

National Electrical Code (NEC), ANSI/NFPA70, (U.S.A.); the

 

AG601; or other applicable regulations.

 

NOTE: The electric supply connection must meet all national

 

 

and local electrical code requirements.

 

Check the oven serial plate before making any electric supply

 

connections. Electric supply connections must agree with data

 

on the oven serial plate. The location of the serial plate is shown

 

in Figure 2-23.

 

A fused disconnect switch or a main circuit breaker (customer

 

furnished) MUST be installed in the electric supply line for each

 

oven cavity. It is recommended that this switch/circuit breaker

 

have lockout/tagout capability.

 

The supply conductors must be of the size and material (copper)

 

recommended. Refer to the wiring diagram inside the machin-

 

ery compartment or control compartment of the oven. Electrical

 

specifications are also listed on the oven's serial plate (Figure

 

2-23) and in the Electrical Specifications table (on Page 5).

 

The oven requires a ground connection to the oven ground screw

 

located in the electrical junction box. (The box is shown in Figure

 

2-24.) If necessary, have the electrician supply the ground wire.

 

Do NOT use the wiring conduit or other piping for ground

 

connections!

CAUTION

Before connecting incoming power to the oven, measure the voltage of each input leg to neutral. The expected voltage is approximately 120V. ANY voltage reading exceeding 130V indicates that the supply has a “high” leg. CONNECTING A “HIGH” LEG TO THE OVEN VOIDS ALL OVEN WARRANTIES. Connecting a “high” leg to the black lead of the oven can severely damage the oven’s electrical and electronic components.

A.Additional Information - Electric Ovens

For electric ovens, a 1-1/4" (32mm) dia. cutout in the back wall of the machinery compartment provides access for the electrical supply connections. Using flexible cables for the electric power supply conductors requires a 1-1/4" (32mm) strain-relief fitting (not furnished with the oven) to enable safe access to the terminal block from which power is distributed to the oven.

B.Additional Information - Gas Ovens

All gas oven electric supply connections are made via the electrical junction box on the rear of the oven, shown in Figure 2-24. The power lines then connect to the oven circuits through the Machinery Compartment Access Panel Safety Switch. This switch interrupts electric power to the oven when the Machinery Compartment Access Panel is opened.

C.Additional Information - Ovens with External Transform- ers (export versions)

Position the transformer on the rear wall of the oven, on the same side as the control compartment, as space permits. Fasten it in place using the supplied mounting hardware.

D.Connection

Refer to the wiring diagram inside the machinery compartment or control compartment of the oven to determine the correct connections for the electrical supply lines. Connect the supply as indicated on the wiring diagram. Be sure to connect the electrical supply ground wire to the oven ground screw located in the junction box on the rear of the oven.
