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. These electrical connections are made at the
terminal block located in the 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 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’s electrical service/relay box.
NOTE: A CIRCUIT SERVICING EACH DRYER MUST BE PROVIDED.
