Insulation Fault Contact / Grid Connection Indicator - Ingecon Sun 250 M220 Indoor Installation Manual

Ingeteam

5.4.5. Insulation fault contact / grid connection indicator

This contact provides an auxiliary function and need not be connected for the unit to operate.
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 230 Vac and a maximum current of 10 A.
each electronics block is assigned its own contact, which detects the isolation operation or failure of the electronics
block in question. If the unit is equipped with the MS kit, only the electronics block contact operating as "master" will
work. For this reason, all contacts must be connected in parallel.
The terminals used are X5.1 and X5.2.
