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.
