15. WIRING THE CONTROLLER
15.1 Overview
Analog and digital signal inputs and outputs are provided for switches, sensors,
contactors, hydraulic valves, CAN communications, RS232 communications and SSI
communications.
The wiring must be carried out by a qualified person.
Attention must be paid to the equipotential bonding for components which are
connected to the unit and which do not have isolated inputs and outputs (equalizing
connection GND). The equalizing currents may destroy components and parts.
The units, the inductive and capacitive accessories as well as the power wiring can
generate strong electric and electromagnetic fields. These fields may be dangerous for
persons having electronic medical aids or appliances (e.g. cardiac pacemakers).
Sufficient distance to these electrical parts must be observed. The switch cabinet must
be labelled accordingly.
Keep all wiring harnesses short and route wiring close to vehicle metalwork. Keep all
signal wires clear of power cables and consider the use of screened cable. Keep
control wiring clear of power cables when it carries analogue information - for example,
accelerator wiring. Tie all wiring securely.
Do not apply power until you are certain the controller high power and signal wiring
is correct and has been double checked. Wiring faults will damage the controller.
15.2 Harness connector wiring
You must use TE CONNECTIVITY connector parts. The harness side connector type:
770680-1
and the corresponding crimp pins:
770520-1
for 16-20 AWG wire
A special hand crimp tool is required for crimping the pins:
58529-1
Try to create the simplest and shortest wiring harness as possible. You can involve the
harness with cable sleeving polyamide or polypropylene spiral, you can protect it from
external influences
