FINAL STEPS
When everything has been connected to the opener...
Replace the control board access
cover. Remove the opener arm from
both mounts and remount it in the
upright position (control board cover
facing down). Failure to re-mount
opener in the upright position will
allow water to enter the opener and
cause damage to the opener control
board.
• Attach Warning Signs
• Trim all Bolts
• Register Your Warranty
Make sure the power
switch to the opener
is turned OFF
before connecting
sensor wiring to the
Mighty Mule 350
terminal blocks.
The wiring cable that
comes with the Mighty
Mule Gate Opening
Sensor has four colored
wires and a braided
wire shield around
them.
Stripback a few inches
of the vinyl (black)
outter cover to expose
the braided SHIELD.
Cut the SHIELD down one side and twist as shown in illustration. Connect the twisted SHIELD, the
YELLOW, the BLACK as well as a separate length of wire, with a WIRE NUT. The other end of the single
length of wire is connected to the COMMON terminal on the Mighty Mule 350 control board.
Connect the RED wire from the sensor to the AUX OUT (H) terminal, and the BLUE wire to the EXIT
terminal on the Mighty Mule 350 control board.
