WARNING

Authorized supplier personnel normally ac- complish the connections for the ventilation system, electric and gas supplies, as ar- ranged by the customer. Following these connections, the factory-authorized installer can perform the initial startup of the oven.

Check the oven data plate (Figure 2-10) before making any electric supply connections. Electric supply connections must agree with data on the oven data plate.

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; or other applicable regulations.

A fused disconnect switch or a main circuit breaker (customer furnished) MUST be installed in the electric supply line for each oven; it is recommended that this switch/ circuit breaker have lockout/tagout capability. The electric supply connection must meet all national and local electrical code requirements. Copper is the recommended material for the electrical supply conductors.

IV. ELECTRIC SUPPLY

Electrical connection is made through a cord and plug. A cord, plug and strain relief is supplied for Domestic oven models, only. International ovens must supply, See Electrical Specifications chart on page 2.

The supply conductors must be of the size and material (copper) recommended to provide the cur- rent required; (refer to the data plate for the ampere specifications). The electric current rating for each conductor supplying a PS724-Series Oven is 1.5A.
