3. Electrical Connections

NOTE

: A wire diagram is located in the front electrical control box for connection data.

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 use of a flexible underwriters laboratory list cord/pigtail (wire

must conform

to ratings 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.

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.

NOTE: A CIRCUIT SERVING EACH DRYER

MUST BE

PROVIDED.
