not to over tighten the strain relief nut. The strain relief accomplishes two tasks: (1)It removes
any wire slack from inside the yaw mount which could cause the wires to rub against the metal
pipe walls inside the yaw mount. (2) The strain relief forms a water tight seal which keeps water
out of the inside of the yaw mount and slip ring.
Step 2: Locate the bag labeled “Electrical Connectors”. Slide a piece of shrink tubing (included)
on all three slip ring wires. Use the electrical butt connectors to connect each generator wire to
one slip ring wire as shown in Step 2 of Figure 4. It does not matter which slip ring wire is
connected to which generator wire.
Step 3: Before applying the shrink tubing, test all three of your crimp connections for
structural integrity and continuity! A poorly crimped electrical connection will negatively
affect the ability for power to transfer from the generator! Firmly pull on both wires coming
out of the butt connector to test for structural integrity. Use a voltmeter to test for continuity.
After you are satisfied with the connections, cover each crimp connection with the shrink
tubing and apply a heat gun to the shrink tubing.
Step 4 (Not shown in diagram): The generator/yaw mount is now sitting on the tower and is
connected to the wires running down the tower pipe. At this time, short the three wires coming
out of the bottom of the tower by connecting all three of these wires together. This will help
prevent the generator from spinning once the blades are attached. Note that shorting all three
of these wires will NOT prevent the blades from spinning; it will only make it more difficult for
the blades to spin. This is done as a safety precaution. Keep these three wires shorted until the
Windtura 500 is ready for operational use.
