Figure 14: PowerCenter with Cover Removed

We recommend the following procedure for making the electrical connections. Please ensure that the

wires do not pull on, or flex, the circuit board.

Step 1:

Remove the cover to expose the circuit board and terminals. The terminals are on the circuit board, as

shown in Figure 15.

Figure 15: Terminals for Electrical Connections

Step 2:

Connect Dump Load leads. This is an optional resistance-heating load that will operate when the batter-

ies are full. Polarity is not important in making this connection. Connecting the extra load can be done at

any time, but if the batteries are full then there will be power on the terminals. This will cause a spark

when attempting to make this connection

The specifications for the dump load are explained on page 8.

If you have already connected the wind turbine and battery bank following the recommended procedure

for installing the wind turbine, you can go to Step 5.

Step 3:

Connect 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 connec-

tions 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 20 seconds to charge all capacitors
