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 four (4) wire service, the neutral. 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 must be removed.

The "LINE POWER" and the "GROUND" connections to the dryer must be made through the knock out hole at the top of the electric service/relay box. A strain relief must be used where the line power/ground wires go into the electric service/relay box.

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 the 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.

NOTE: A CIRCUIT SERVING EACH DRYER MUST BE PROVIDED.
