Earth Fault Contact / Grid Connection Indicator
The inverter is equipped with a normally-open potential-free contact, which can perform
one of the following two functions:
Insulation failure detection in the DC circuit.
Indicator to show that the unit is connected to the power grid by means of its internal
contactor.
The equipment always takes measure of the Earth Fault although the contact is used in
Grid connection indicator function.
The equipment is factory configured to perform one or other function; the function
option must be expressly requested when the order is sent to Ingeteam Energy S.A.
The normally open contact admits a voltage of 230 Vac and a maximum current of 10 A.
The contact is accessed through the cabinet side PGs.
3.3
Access to the auxiliary connections
In some PV installations the inverter needs to be connected to auxiliary equipment such
as solar radiation sensors, thermal sensors, anemometers, etc.
Consult the communication accessory installation manual «AAX2002IKI01
Communication accessories Installation Manual.»
For enhanced operation, the cables transporting these auxiliary signals should
be kept at a distance from the power cables.
In these models the auxiliary signals are directly connected to the analogue input card
«AAP0016 Tarjeta de Entradas Analógicas».
