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: Agrounding connection (terminal lug) is provided in the dryer’s 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.
