SECTION 2 - INSTALLATION
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.
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,
have the electrician supply the ground wire.
Do NOT use the
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 2-15. The
power lines then connect to the oven circuits through safety
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 2-15). The equipotential ground connection
must meet all applicable national and local code requirements.
