The neutral will only be used on 4-wire service. This is typical
for 380-416V, 50 Hz.
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.
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.
A ground lug is provided in the rear electrical box to connect
your service ground.
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.
