cable tie to the cable at the mast top. Fill both
cable holes in the mast with sealant.

Take the piece of masthead unit cable that you
cut off earlier and connect the cable into the
back of the WIND 3150 display unit. Run the
cable between the display unit and the cable
junction box:
Keep the cable away from other cables,
engines, fluorescent lights and power
inverters.
Secure the cable at regular intervals.

Cut the cable to length, allowing extra length
for terminating the cable in the joining box.
Feed the end of the cable through the other
gland on the cable junction box. Strip the cable
jacket off and terminate wires on the terminal
block, matching the wire colours.

Wire the display unit power/data cable:
The unit requires 12 V DC power. Fit a
power switch and fuse to the power supply
or power the unit from a fused auxiliary
switch. The fuse should be 1 A for up to five
instruments.
The output to external beepers and lights is
switched to power negative by the WIND
3150 to sound the alarm. If the external
beepers and lights require more than
250 mA DC total, fit a relay.
A single unit can be wired as shown below:
