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. Providing local codes permit, power connections
to the dryer can be made by the use of a flexible underwriters laboratory listed cord/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 wire(s) enter the dryer electrical service (relay) box.

a. Gas Model Dryers

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.

NOTE:

A CIRCUIT SERVICING EACH DRYER

MUST BE

PROVIDED.
