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.
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.
