5.3 Connecting the Small Wind Turbine System
Grounding the small wind turbine system:
The small wind turbine system is not grounded through the Windy Boy Protection Box. You must
ground the small wind turbine system by other means than the Windy Boy Protection Box. Observe
all manufacturer instructions when doing so.
1. If there are rectifiers and overvoltage protection between the small wind turbine system and the
wind power inverter, remove the rectifiers and overvoltage protection.
2. Attach the M25 cable gland to the enclosure opening for the small wind turbine system.
3. Unscrew the cable gland's lock nut and pass it over the cable.
4. Pass L1, L2, and L3 of the small wind turbine system through the cable gland and connect to the
Alternator connection terminal.
5. Tighten the lock nut firmly to the cable gland.
Destruction of the Windy Boy Protection Box due to excessive power from the small wind
turbine system.
• Observe the maximum power that can be connected (see section 10 ”Technical
Data”, page 22).
• If the power of the small wind turbine system exceeds the maximum power that can be
connected to the Windy Boy Protection Box, use several Windy Boy Protection Boxes in the
system.
