VI. 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: All aspects of the electrical supply connection must
comply with current IEC/CEE requirements and with all
applicable local, national, and international codes.
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. The circuit breaker/disconnect must have 3mm
contact gaps breaking all poles of the supply. It is recommended
that this circuit breaker/disconnect have lockout/tagout capability.
The supply conductors are to be 90°C-rated copper wiring.
Additional wiring information is shown on the wiring diagrams
in Section 5,
Electrical Wiring Diagrams and inside the machin-
ery 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 Figures 2-13 and 2-14.) The ground connection must comply
with current IEC/CEE requirements and 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 2-13. The
power lines then connect to the oven circuits through safety
switches located inside the machinery compartment and each
blower motor compartment. These switches interrupt electric
power to the oven when the Machinery Compartment Access
Panel is opened, OR when either of the blower or rear shrouds
is removed.
B. Additional Information - Electric Ovens
A 51mm dia. cutout in the back wall of the machinery compartment
provides access to the electrical supply connections. See
Figure 2-14. The actual wiring connections are made at the
terminal block located inside the side compartment of the oven.
Using flexible cables for the electric power supply conductors
requires a 51mm strain-relief fitting (not furnished with the
oven) to enable safe access to the terminal block.

C. 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 national or local codes, connect an equipotential
ground wire to the lug next to the
symbol (shown in Figures
2-13 and 2-14). The equipotential ground connection must
meet all applicable national and local code requirements.

V. FINAL ASSEMBLY
1. Install the crumb trays underneath the conveyor as shown
in Figure 2-12. First, place the inside edge of the tray onto
the retainer (shown in Figure 2-9). Then, swing the outside
edge of the tray up and into place.
2. Press the conveyor end stop and rear stop down over the
edge of the conveyor frame. See Figure 1-1 (in Section 1,
Description).
