Grounding
A ground (earth) connection must be provided and installed
in accordance with local, state, and national regulations or
codes of the country of origin. In the absence of these codes,
grounding must conform to applicable requirements of the
National Electrical Code ANSI/NFPA NO. 70-LATEST EDITION,
or in Canada, the installation must conform to applicable
Canada Standards: Canadian Electrical Codes Parts 1 & 2
CSA C22.1-1990 or LATEST EDITION. The ground connection
may be to a proven earth ground at the location service panel.
For added personal safety, when possible, it is suggested
that a separate ground wire (size per local codes) be
connected from the ground connection of the dryer to a
grounded cold water pipe. Do not ground to a gas pipe or hot
water pipe. The grounded cold water pipe must have
metal-to-metal connection all the way to the electrical ground.
If there are any nonmetallic interruptions, such as, a meter,
pump, plastic, rubber, or other insulating connectors, they
must be jumped out with a wire (size per local codes) and
securely clamped to bare metal at both ends.
Important
For personal safety and proper operation, the dryer
must be grounded.
Provisions are made for ground connection in each dryer at
the electrical service connection area.
Warning
Electrical Grounding Instructions – This dryer is
equipped with a 3-prong (grounding) plug for your
protection against shock hazard and should be plugged
directly into a properly grounded 3-prong receptacle. Do
not cut or remove the grounding prong from this plug.
Electrical Connections
A wiring diagram is located behind the control panel for
connection data.
If local codes permit, power to the dryer can be made by the
use of a flexible UL listed power cord/pigtail (wire size must
conform to rating of 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.
For CE Models Only
The means for disconnection from the supply must be
incorporated into wiring having a minimum contact separation
of 3.0 mm in all poles.
Single-Phase (1ø)
Wiring Connections/Hookup
The electrical input connections are made into the rear service
box located at the upper right area of the dryer. The ground
connection is made to the copper lug, also provided in this
box. To gain access, the service box cover must be removed.

Caution
The dryer must be grounded. A ground lug has
been provided for this purpose.
Input connection wiring must be sized properly to handle the
dryer’s current draw. This information is printed on the dryer’s
data label.
Important
A strain relief must be used where the input wiring
enters the oven assembly.
Electrically Heated Models Only
The electrical input connections are made at the rear service
box located at the right upper section of the dryer. The ground
connection is made to a copper lug also provided in this
area. To gain access, remove rear service cover.
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 (if present) is done
internally to the dryer by the factory at the oven contactor. No
single-phase (1ø) input connection is required on a 3-phase
(3ø) dryer.
The neutral will only be used on 4-wire service. This is typical
for 380-416V, 50 Hz.
Caution
The dryer must be grounded. A ground lug has
been provided for this purpose.
Input connection wiring must be sized properly to handle the
dryer’s current draw. This information is printed on the dryer’s
data label.
