A ground lug is provided in the rear electrical box to connect your service ground.
2) 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.
b. Electrically Heated Models Only
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.
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.
IMPORTANT:
A strain relief
must be
used where the
input wiring enters the oven assembly.
