Wiring the eHorn with the Supplied Leads
The power connection is made via the external leads.
To wire the 24 Vdc Model eHorn:
1. Connect the positive (+) lead of the power source to the
red wire.
2. Connect the negative (‑) lead of the power source to the
black wire.
Wiring the eHorn with User-Supplied Leads
If you are not using the external leads supplied with the eHorn,
follow these steps:
1. Strip no more than 0.25 inch (6 mm) of wire insulation
from the ends of the power leads. If you are using stranded
wire, be sure that there are no loose strands outside the
connector plug that could touch the adjacent lead and cause
a short circuit. Torque the terminal screws to 4.4 in‑lb
(0.5 Nm) maximum.
2. Connect the power source positive (+) lead to the (+)
terminal of the connector.
3. Plug and connect the power source negative (‑) lead to the
(‑) terminal of the connector plug as shown in Figure 5 on

4. Plug the DC power connector into the power input
connector on the printed circuit board.
