1) 3-Phase (3

ø

) Wiring Connection/Hookup

For gas dryers manufactured for operation at 3-phase (3

ø

),

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

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 some-

times 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 SERVING EACH DRYER MUST BE PROVIDED.

Providing local codes permit, power to a 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.
