Step 3:

Mount the wind turbine tower adapter to the top of the tower using six M10-1.5 x 20mm bolts and six

washers. We require applying Loctite 242 (Thread Locking Compound) to the threads prior to installation

to reduce the likelihood of loosening due to vibration. Use a torque wrench to achieve the proper fastener

torque on the tower mounting bolts. The required torque is 45 ft-lbs.

Step 4:

Complete the turbine wiring to the PowerCenter before adding the blades. This is recommended so that

you can test the DC polarity of the wiring by spinning the alternator by hand. It is very important that the

polarity [positive (+) and negative (-)] is correct when the turbine is connected to the PowerCenter. The

best way to ensure this is to complete the wiring and then test the polarity with a Volt-Ohm-Meter or the

polarity checker built into the PowerCenter. Do not use the polarity checker on the PowerCenter cir-

cuit board with blades on and the turbine turning under wind power because the voltage will be

too high for the polarity check circuitry.

To use the PowerCenter’s polarity check, first connect the suspected negative wire to the terminal

marked “TUR - “, then touch the wind turbine positive wire to the “POLARITY CHECK” pad on the control-

ler. The green LED should light when the alternator is turned by hand. If it does, connect the turbine pos-

itive wire to the “TUR +” terminal. If the red LED lights, reverse the leads and check again.

Wiring recommendations are provided in Section 7 and in Appendix 1, section D. Turning the al-

ternator by hand will provide enough voltage to make this check. Carefully mark the positive and

negative electrical leads for later reference.

We recommend that you connect the battery bank to the PowerCenter at this point so that you can

use the Stop Mode to keep the blades from turning during the turbine and tower raising process.

To connect the battery leads, first connect the battery negative (-) wire to the terminal marked “BAT –“.

With the battery positive wire touch the pad marked “POLARITY CHECK”, if red LED (D80) lights, the

connections are backward, double check everything to find the cause. The green LED (D70) should

come on, if it does leave the wire in contact with the “POLARITY CHECK” pad for 5 seconds to charge all

capacitors and avoid a spark when making the battery connection. Quickly connect the battery positive

wire to the terminal marked “BAT +”. The system will not operate correctly and could be damaged if the

polarity is reversed.
