FOR PS624-SERIES OVENS.
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
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
