3. Electrical Connections

NOTE: A wiring diagram is included with each dryer and is affixed to the rear upper right guard panel

of the dryer.

The only electrical input connections to the dryer are the 3-phase (3ø) power leads (L1, L2, and L3), GROUND,

and in the case of 4 wire service, the neutral. These electrical connections are made at the wire leads located

in the electric service and relay box at the rear, upper left hand corner of the dryer. To gain access into this

service box, the service cover must be removed.

Providing local codes permit, power connections to the dryer can be made by the use of a flexible under-

writers laboratory listed cord and pigtail (wire size must conform to rating of the dryer), or the dryer can be

hard wired directly to the service breaker. In ALL cases, a strain relief must be used where the wires enter

the dryer electrical service (relay) box.

a. Gas Models and Steam Models Dryers ONLY

These electrical connections are made at the terminal block located in the electric service/relay box at the

rear, upper left hand corner of the dryer. To gain access into this service box, the service cover (upper

back guard) must be removed.

b. Electric Model Dryers ONLY

For electric model dryers made to operate at 208 VAC, 230 VAC, or 240 VAC, the electrical input

connection is made into the terminal block located at the upper rear of the dryer. For electric model dryers

made to operate at 380 VAC, 416 VAC, 440 VAC, or 480 VAC, the electrical input connection is made to

the oven relay 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 which is affixed to the

rear, upper right hand corner of the dryer.
