a) Electrically Heated Models Only
The only electrical input connections to the dryer are the 3-phase (3ø) power leads (L1, L2, L3,
and sometimes neutral) and ground. Single-phase (1ø) power for the control circuit and for any
single-phase (1ø) motors (if present) is done internally to the dryer by the factory at the oven
contactor. No single-phase (1ø) input connection is required on a 3-phase (3ø) dryer.
CAUTION: The dryer must be grounded. A ground lug has been provided for this purpose.
Input connection wiring must be sized properly to handle the dryer’s current draw. This
information is printed on the dryer’s data label.
IMPORTANT: A separate circuit servicing each dryer must be provided.
The electrical input connections are made at the electric oven contactor located inside the
assembly at the rear center upper section of the dryer. The ground connection is made to a
copper lug also provided in this area. To gain access, remove oven rear service cover.
IMPORTANT: A strain relief must be used where the input wiring enters the oven assembly.
