Section 1.1: Wiring the EHU
1.
Trim approximately 1.5 inches of the outer jacket of the control cable.
2.
Remove the outer foil shield, the support thread, and cut the shield wire off.
3.
Attach electrical tape at the end of the trimmed control cable jacket so that there is no chance for a short.
4.
Remove 0.25 inches of the insulation from each of the individual 22 AWG wires, leaving bare copper.
Tin-
ning of the copper wire ends with solder is NOT recommended by the connector manufacturer.
Figure
1.10
shows the control cable should look like when you are finished with the trimming.
5.
Dip each of the copper wires into connector protector before inserting into the terminal plug.
Figure 1.11
shows what the connector protector will look like.
6.
The terminal header assembly consists of the terminal header and the terminal plug as shown in. The
plug is shipped loosely attached to the header. Remove this plug when wiring and firmly plug back in
when completed (use dielectric grease on this terminal plug to prevent moisture ingress/corrosion).
7.
Follow the wire sequence in
figure 1.13.
Be careful to ensure that there are no bare wires protruding out
from the terminal clamps, to avoid potential shorts. Also make sure you are clamping down on bare wire,
and not the insulation of the wire
The wiring sequence for the EHU is also imprinted on the PCB that the
terminal header is mounted on (located inside the EHU), as shown in
figure 1.12
. Pay no attention to the
second row of imprinted text, these pins are for use in the manufacturing of the board itself and are of no
use to you.
Figure 1.12
shows a blue line crossing out the text in question. The orange circle shows the
correct wiring sequence.
