3.Electrical Connections

NOTE: A wiring diagram is included with each dryer and is affixed to the panel inside the right side control cabinet.

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. These electrical connections are made at the power distribution block located in the left side control cabinet.

Providing local codes permit, power connections to the dryer can be made by the use of a flexible Underwriters Laboratory 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) enter the dryer electrical service (relay) box.

NOTE: A CIRCUIT SERVING EACH DRYER MUST BE PROVIDED.

4.Main Grounding

Grounding (earth) connections 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 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 dryer at the left side control cabinet.

For added personal safety, when possible, it is suggested that a separate ground wire (sized per local codes) be connected from the ground connection of the dryer to a grounded cold water pipe. DO NOT ground to a gas or hot water pipe. The grounded cold water pipe must have metal to metal connections ALL the way to 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 (computer), an earth (zero) ground is required.

NOTE: Grounding via metallic electrical conduit (pipe) is not recommended.
