The battery harness wire has an 
in-line fuse that must be placed 
inside the battery box when 
connecting the battery to the 
opener. The illustration to the 
right shows the best placement 
for the battery harness wire and 
connector inside the arm.
The wires from the battery harness, receiver, transformer or 
solar panel, and any accessories that have been installed will 
be routed down the sides of the opener and out the strain 
relief slot in the back of the opener. 
It is IMPORTANT that the wires lay flat and run inside the 
routing pins at the back of the opener and out the strain 
relief slot without being pinched when 
the control board access cover is 
replaced. See the illustrations to the 
right and below.
