The electrical input connections are made at the rear service box located at the right upper section of the dryer. The ground connection is made to a copper lug also provided in this area. To gain access, remove 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.

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