Electrically Heated Models Only
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.
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 strain relief must be used where the input wiring
enters the oven assembly.

service box cover must be removed.
The neutral will only be used on 4-wire service. This is typical
for 380-416V, 50 Hz.
