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.
