Providing local codes permit, power to the dryer can be made by use of a flexible U.L. listed power
cord/pigtail (wire size must conform to the rating of the dryer), or the dryer can be hard wired directly
to the service breaker panel. In both cases, a strain relief must be installed where the wiring enters the
dryer.

The only electrical input connections to the dryer are the 3-phase (3ø) power leads (L1, L2, L3, and sometimes
Neutral) and ground. Single phase (1ø) power for the control circuit and for any single-phase (1ø) motors

3-phase (3ø) dryer.
