5.5.6. Insulation fault contact / grid connection indicator
The inverter incorporates a normally open volt-free auxiliary contact. It can be used for one of two functions:
•
Detection of insulation fault in the DC circuit.
Open contact: There is no insulation fault in the DC circuit.
Closed contact: There is an insulation fault in the DC circuit.
•
Indicator showing that the unit is connected to the mains via its internal contactor.
Open contact: Internal contactor for connecting to the grid is open; the inverter is not connected to
the grid.
Closed contact: Internal contactor for connecting to the grid is closed; the inverter is connected to
the grid.
The unit always measures the insulation separately from the contact configuration.
The configuration of the equipment to make the contact perform one or another function is factory set
and must be specifically requested from Ingeteam at the time of ordering.
This normally open contact withstands a voltage of 240 Vac and a maximum current of 10 A.
The terminals used are X2.5 and X2.6
