Effective Strain Relief for ADCU Terminal Connections

Due to both the potential number of wires that connect to the

rear of the ADCU and the dynamic environment aboard ship, it is

critical that the terminal connections be properly strain-relieved

using tie-wraps (a number of which are included in the GyroTrac

kitpack).

Some things to consider when strain-relieving wires:

• There should be no tension on the wires

connecting to the terminal strips. Removing slack

is important, but the wires should not be taut.

• Leave enough slack in the wires to allow easy

access to the ADCU’s rear panel in case of future

software upgrades.

• If the cable is equipped with a ferrite, the ferrite

should be as close as possible to the terminal

connections.

• Strain-relieve wires and cables as close to the

ferrite as possible. A good arrangement includes a

tie-wrap behind the ferrite (on the side furthest

from the ADCU); an ideal design includes a tie-

wrap on either side of the ferrite.
