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 the use of flexible underwriters laboratory listed cord or 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 wires enter the dryer electrical service (relay) box.
4.
Grounding
A ground (earth) connection must be
provided and installed in accordance with
state and local codes. 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.
NOTE: A grounding connection (terminal lug) is provided in the dryers electrical service box at rear.
For added personal safety, when possible, it is suggested that a separate ground wire (sized per local code)
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 no. 4 copper wire and securely
clamped to bare metal at both ends.
IMPORTANT: For personal safety and proper operation, the dryer must be grounded. For proper
operation of the microprocessor controller (computer), an earth (zero) ground is
required.
NOTE: Grounding via metallic electrical conduit (pipe) is not recommended.
These electrical connections are made at the terminal block located in the electric service box at the rear,
upper right hand corner of the dryer. To gain access into this service box, the service cover must be
removed.
NOTE: A CIRCUIT SERVICING EACH DRYER MUST BE PROVIDED.
