12.1 Checking the Small Wind Turbine System for a Ground Fault
If the inverter displays event numbers "35", "36" or "37", there is a high probability of a ground fault
in the system.
Check the small wind turbine system for ground connection as described below:
1. Remove the Electronic Solar Switch.
2. Wait until LEDs, display and if applicable the fault indicator have gone off.
DANGER!
Danger to life due to high voltages in the inverter.
• Stop the small wind turbine system and secure against restart.
• Disconnect the line circuit breaker and secure against re-connection.
• Disconnect the multi-function relay, if available.
DANGER!
Danger to life due to high voltages in the inverter.
The capacitors in the inverter require 5 minutes to discharge.
