The electrical input connections are made to the contactor located inside the electric oven 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.
2) 3-Phase (3ø) Wiring Connections/Hookup
The electrical connections on
ALL
3-phase (3ø) gas and steam dryers are made into the rear service
box located at the upper left area of the dryer. The electrical connections are made at the power
distribution block located in the service box. The ground connection is made to the copper lug, also
provided in this box. To gain access, the service box cover
must be
removed.
The neutral will only be used on 4-wire service. This is typical for 380-416V, 50 Hz.
