Electrical Installation

Twin Disc, Incorporated

Each single lever harness is designed to connect to the Control Head at one end, and to the EC300 Control’s J1, J2, or J3 connector at the other end. Use

Connector J1 if only one Single Lever Control Head is used. Use Connectors

J1 and J2 if two Single Lever Control Heads are used.

Install the Control Head harness as follows:

2.

3.

Note: The Control Head may be removed from the dash if this facilitates making the connection. If it is removed, then reinstall it after the connections have been made.

Note: Provide enough length in the harness to allow removal of the Control Head in the future.

Refer to General Electrical Installation Guidelines for harness routing criteria.

1.

Connect the circular connector end of the Control Head harness to the

Control Station 1 (main/most used) Single Lever Control Head.

Note: Align the large connector key with the large keyway and push the connector into place. Then, turn the connector’s collar until the engagement snap is felt.

Ensure that the Single Lever Control Head is firmly mounted.

Route the Control Head harness to the EC300 Control.

4.

5.

6.

7.

Connect the Control Head Harness plug to the J1 receptacle of the

EC300 Control.

If applicable, repeat Steps 1 through 4 for connecting additional Control

Stations using J2 for the second Control Head and J3 for the third Control

Head.

If J2 and/or J3 are not used, install a connector kit into these receptacles to seal the connector. See System Drawing for Connector Plug Kit p/n.

Secure all harnesses to a supporting structure with clamps or cable ties at 406 mm (16 in.) intervals.
