Block the wind generator if a braking system is available.
3.
Disconnect the inverter DC input cable, isolate it, mark it and protect it.
4.
Disconnect the Vac cable.
5.
Wait 10 minutes for the internal capacitances to discharge, the hot parts to cool and the inverter’s fan blades
to stop turning.
6.
Open the door and discharge the Vbus by means of a suitable discharge resistance between the +VBUS and
-VBUS. Check there is no voltage
To carry out steps 2, 3, 4, 5 and 6, it will be necessary to use the PPE indicated in Section “4.4.3. Personal
Protection Equipment (PPE)” in this document for work with live parts.
Any work carried out which implies a modification of the original electrical settings must be proposed
