C.
208 VAC AND 230/240 VAC ARE NOT THE SAME. When ordering,
specify exact voltage.
When fuses are used they must be dual element, time delay, current
limiting, class RK1 or RK5 ONLY. Calculate/determine correct fuse
value, by applying either local and/or National Electrical Codes to listed
appliance amp draw data.
Circuit breakers are thermal-magnetic (industrial) type ONLY. For others,
calculate/verify correct breaker size according to appliance amp draw
rating and type of breaker used.
Circuit breakers for 3-phase (3ø) dryers must be 3-pole type.

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 UL 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) enters the dryer electrical service
(relay) box.
