General Component Installation Guidelines

Ensure a suitable location is chosen for mounting the EC300 Control(s),

Control Head(s), Twin Disc Display(s), and any other components. EC300

Controls should be mounted near the engines in a location reasonably free from direct splash and spray, and protected from mechanical abuse. See

Appendix - A for Environmental Specifications. When selecting the location

for mounting the components, consideration should be given to any pushpull cable routing in order to avoid sharp bends or excessive lengths. The mounting surface should be flat, or shimmed so that the control enclosure is secured without distortion to the bottom plate. Controls should not be mounted on the engines unless they are protected by a heat shield and mounted to a vibration-damped plate.

Choose a location that meets the following criteria:

‰

It is not on any drivetrain component.

‰

‰

It is away from heat sources.

It is clear of service and access areas.

‰

‰

It is away from AC power and high current conductors.

It is protected from submersion or splash.

‰

‰

It will not provide a “step” for personnel.

It is a minimum of 1 m (3.3 ft) away from alternators, generators, communications equipment, and associated wiring.

‰

‰

It is away from high vibration.

It provides easy access for routing, connecting, and adjusting the push-pull cable, if used.

‰

‰

It is convenient for accessing the electrical connections.

Control equipment and displays are to be so placed or protected as to minimize the likelihood of sustaining damage from the condensation of moisture, accumulation of dust, oil vapors, steam, dripping liquids, or from activities around their location.

There are other factors to consider when choosing a mounting location for the

EC300 Controls and Servo Actuators.

Push-pull cable installation should meet the following criteria:

‰

Cables should be minimum length possible.

‰

Any cable bends should have no sharp bends. Install with the maximum possible bend radius. Refer to cable manufacturer’s specifications.

‰

‰

‰

Cables must be located away from hot surfaces.

Cables must be clear of service or access areas.

Cables must be Morse Series 33 RED JAKET ® Supreme or equivalent.

Electrical wiring and routing should meet the following criteria:

‰

Wiring must be minimum practical length.

‰

‰

Wiring must be located away from high current conductors and devices.

Wiring must be located away from hot surfaces.

‰

‰

Wiring must be clear of service and access areas.

Wiring should be at least 1 m (3.3 ft) away from communications equipment, antennas, and associated leads.

‰

Wiring should be at least 1 m (3.3 ft) away from alternators, generators, and ignition systems.

‰

Wiring should have drip loops where required, especially at the controls.

Use the correct fasteners and mounting hardware as follows:

‰

Use any fasteners and mounting hardware as supplied from Twin

Disc Incorporated with the component.

‰

‰

Use stainless steel fasteners unless otherwise specified.

Use lock washers as specified.
