DC circuit breaker

μWind units (with or without transformers) may have an optional DC isolating switch.
There are several different models, although they all have the same electrical properties.
The advantage provided by this isolator is that it can isolate under load in case of emergency.
In any case, we recommend that other than in the case of an emergency, the unit be shut
down by means of the display before isolating.

As long as the wind generator receives wind, the DC cables will carry potentially dangerous voltage
levels.
Never handle the connections before disconnecting the inverter from the grid and the wind generator.
Ingecon® μWind Interface (IWI) Connector
You may optionally request the inverter to be fitted with a
connector for connecting to the Ingecon
®
μWind Interface.

μWind units with transformer are supplied with the inverter and transformer in
separate boxes. They must be connected when installed using the cable supplied with the
transformer.
The connectors to link are as shown in the figure.
