INSTALLATION

VI. ELECTRICAL CONNECTION

Check the oven data plate before making any electric supply connections. Electric supply connections must agree with data on the oven data plate. A typical oven data plate is shown in Figure 2-34 (on Page 2-24).

NOTE: When the oven is installed, it must be electrically grounded in accordance with current IEC/CEE requirements and also with local codes.

The electrical installation, including the service connection, must comply with current IEC/CEE requirements and to local codes. The installation must undergo a complete electrical check before operating the oven.

Special attention must be given to the polarity of the supply when connecting to oven input terminals.

All connections are made at one common connection at the back of each oven. Refer to Figures 2-32 and 2-33.

NOTE: At the installation location, it is required that the electrical supply for each oven incorporates a main circuit breaker (not furnished). The circuit breaker must have 3mm contact gaps breaking all poles of the supply.

WARNING: If your electrical supply has fast-acting circuit breakers, then the initial starting current of the blower motors in Model PS360WB-U and PS360WB-L may trip the breakers. It is suggested to use slow-acting circuit breakers with these models.

For further electrical information, refer to the wiring diagram.

WARNING: The connections to the exhaust system, electrical supply, and gas supply must follow the installation instructions. Initial start-up of the oven can be performed only by an authorized agent.
