5.8 Harness Wiring Standards
The following are general “good practice” guidelines for wire harness design
and installation. It is the responsibility of the machine designer to follow
standards appropriate to the application type and to the geographical territory
where the machine will be operated. These recommendations do not replace
in any way any industrial standards or legal requirements. Please be aware
however that any customer installed components, which are integral to the
engine or aftertreatment system, are governed by mandatory requirements to
ensure the correct operation of the complete system installation. These
specific requirements are covered in sections 6 and 9.
5.8.1 Connectors
It is strongly recommended that high quality sealed connectors are used
throughout. Automotive standard components are not necessarily suitable as
they are often only designed for a very low number of disconnect/reconnect
cycles.
Connectors should be horizontally mounted rather than vertically mounted to
prevent ingress of water/chemicals. Whenever possible, connectors should be
mounted such that they are protected from direct exposure to extreme cold.
Connectors can be damaged by frost if water does penetrate the seals.
Cables should not bend close to the connector seals, as the seal quality can
be compromised.
The correct wire seal must be selected for the diameter of wire used.
Cables should be selected of an appropriate cross section for the current and
voltage drop requirements
Where large numbers of wires go to the same connector, it is essential that no
single wire is significantly shorter than the others, such that it placed under
exceptional strain.
Note: All electrical components and connectors are not designed to
withstand direct exposure to high-pressure water.
