IV. ELECTRICAL SUPPLY

WARNING

Authorized supplier personnel normally accomplish the connections for the ventilation system, electric supply, and gas supply, as arranged by the customer. Following these connections, the factory-authorized installer can perform the 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 Canadian Electrical Code, CSA C22.2; the Australian Code, AG601; current IEC/CEE requirements (CE countries); or other applicable regulations.

NOTE: All aspects of the electrical supply connection must comply with all applicable local, national, and international 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 1-1 (in Section 1, Description).

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 circuit breaker/disconnect have lockout/tagout capability. For CE installations, the circuit breaker/disconnect must have a minimum of 3mm contact separation breaking all poles of the supply.

The supply conductors must comply with all applicable local, national and international codes. Supply conductors must be insulated copper wiring, #18 AWG (American Wire Gauge) or equivalent. Additional wiring information is shown on the wiring diagrams in Section 5, Electrical Wiring Diagrams and inside the machinery compartment of the oven.

SECTION 2 - INSTALLATION

The oven requires a ground connection to the oven ground screw located in the electrical junction box. (The box is shown in Figure 2-14.) The ground connection must comply with all

applicable local, national, and international codes. If necessary,

ENGLISH

have the electrician supply the ground wire. Do NOT use the

power lines then connect to the oven circuits through safety

wiring conduit or other piping for ground connections!

 

A. Additional Information - Gas Ovens

All electric supply connections are made via the electrical junction box on the rear of the oven, shown in Figure 2-14. The

switches that interrupt electric power to the oven:

•When the Control Compartment Access Panel is opened;

•When the Machinery Compartment Access Panel is opened,

OR

•When the rear panel is removed.

B.Connection

Refer to the wiring diagram inside the machinery compartment, or in Section 5 of this Manual, to determine the correct connections for the electrical supply lines. Connect the supply as indicated on the wiring diagram.

If required by local, national or international codes, connect an equipotential ground wire to the lug next to the symbol (shown in Figure 2-14). The equipotential ground connection must meet all applicable national and local code requirements.
