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.
