5. 3-Phase (3ø) Wiring Connections/Hookup
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 is done internally to the
dryer. No single-phase (1ø) input connection is required on a 3-phase (3ø) dryer.
IMPORTANT: A CIRCUIT SERVICING EACH DRYER
MUST BE
PROVIDED
.
a. Gas Models and Steam Models ONLY
1) 3-Phase (3ø) Wiring Connections/Hookup
For gas dryers and steam dryers manufactured for
operation at 3-phase (3ø), the electrical connections are
made at the power distribution block located in the service
box at the rear, upper left corner of the dryer. The ground
connection is made to the copper lug also provided in this
box. To gain access to the service box and contactor, the
service box cover
must be
removed.
Providing local codes permit, power to a gas
dryer or steam dryer can be made by the use
of a flexible U.L. listed power cord or pigtail
(wire size
must conform
to rating of dryer),
or the dryer can be hard wired directly to the
service breaker panel. In
ALL
cases, a strain
relief
must be
installed where the wiring
enters the dryer and service box area.
b. Electric Models ONLY - 3-Phase (3ø) Hookup
The electrical input connection is made into the electric oven contactor located at the upper rear of the
dryer. Input connection wiring
must be
sized properly to handle the dryer’s current draw. This
information is printed on the dryer’s data label.
