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
1) 3-Phase (3ø) Wiring Connections/Hookup
For gas 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 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.
