The purpose of the diversion/dump load is to help keep the turbine under control under two conditions without triggering the external braking systems (both 

electrical and mechanical). Those conditions are:

- Inverter disconnected from the electrical grid. Without the inverter on the grid, the turbine would turn freely, unloaded. This calls for a method to avoid runaway 

and keep the turbine within its specified operating range, reducing the need to invoke mechanical protection mechanisms (disc brakes, pitch control, etc).

- Exceeding the maximum power of the inverter. At sites where the maximum power rating of the inverter will be exceeded only a few times per year, it’s pos-

sible to employ a dump load instead of an inverter with a higher power rating. During strong winds, the excess power that can’t be handled by the inverter is 

shunted to the resistive load.

CONNECTION

To connect the two wires, coming from Diversion load resistor to the terminal requires releasing the terminal spring clamp. This is accomplished as follows: 

1) Insert the flat blade of a screw driver into the connector release hole.

2) While holding the release open, insert the appropriate wire into the connector hole marked CLAMP

3) Hold the wire in place in the clamp and remove the screwdriver from the RELEASE hole to clamp the wire in the terminal.

The correct sizing of the dump load resistor is dictated by the characteristics of the individual site and the characteristics of the 

individual wind turbine, and is beyond the scope of this guide. The determination of the resistor value (ohms) and dissipation rating 

(watts) is the resposnsibility of the wind turbine system designer or the customer.

Remember that the values IABR(max) and IDC(max) must never exceeded.

The Wind Interface may not always be able to prevent runaway (for instance, if the generator fails), therefore it is necessary to have an 

external Safety Brake circuit, electrical and/or mechanical, that brakes the system.

To connect the two wires, coming from DC side of inverter, to the terminal requires releasing the terminal spring clamp. This is accomplished as follows: 

1) Insert the flat blade of a screw driver into the connector release hole.

2) While holding the release open, insert the appropriate wire into the connector hole marked CLAMP

3) Hold the wire in place in the clamp and remove the screwdriver from the RELEASE hole to clamp the wire in the terminal.

Tachometer output (WIND SPEED connector) is an open collector source. The generated pulse train has frequency identical to the generator frequency.  

Max pull up voltage = 24Vdc; zero level = 1.4Vmax; max current = 1mA. The pulse train is generated from two of the wind turbine input phases (1 and 2). A 

hardware filtering optimizes the frequency reading in the range 5-200Hz.

This link is mandatory if in the inverter is uploaded a power curve defined in term of frequency.

To connect the two wires, coming from +/- WT connector of inverter, to the terminal requires releasing the terminal spring clamp. This is accomplished as 

follows: 

1) Insert the flat blade of a screw driver into the connector release hole.

2) While holding the release open, insert the appropriate wire into the connector hole marked CLAMP

3) Hold the wire in place in the clamp and remove the screwdriver from the RELEASE hole to clamp the wire in the terminal.

Wiring must be done with the inverter disconnected from the grid. Both the grid-side switch (S2) and the turbine side switch (S1) must be 

open. The turbine itself must be parked and in safty mode

To connect the three wires, coming from generator, to the terminal requires releasing the terminal spring clamp. This is accomplished as follows:

 

1) Insert the flat blade of a screw driver into the connector release hole.

2) While holding the release open, insert the appropriate wire into the connector hole marked CLAMP

3) Hold the wire in place in the clamp and remove the screwdriver from the RELEASE hole to clamp the wire in the terminal.
