Remote Triggering Kit - Ingeteam Ingecon Sun 250 TL Installation Manual

Installation manual
To avoid this situation, check that there are no insulation faults in the grounded pole by inspecting the installation.
This procedure should be carried out in compliance with the security measures described in this manual.
Turn off the unit to perform the following procedures:
1. Measure the voltage between positive and negative in the panel (Voc)
2. Measure the voltage between the positive pole and ground (VP)
3. Measure the voltage between the negative pole and ground (VN)
The PV array will be properly insulated if VP and VN are less than the value of Voc divided by two.
If VP or VN have a value greater than Voc/2, the PV array will have faulty insulation in one of its parts.
The protection will be monitored by the inverter control, and when the breaker opens the connection of the PV array
to ground, the control will shut down the unit, triggering the 0x0200 DC Protection alarm.
In 250 to 625 kW TL models in which the MS option has been added, the 4-pole thermomagnetic circuit breaker
shall be placed in cubicle A.

5.6.3. Remote triggering kit

In some countries, current regulations require remote protection to be implemented in inverters to open the connec-
tions. To achieve this a kit may be used which opens the thermomagnetic circuit breaker on the grid connection.
To activate the coils that make the thermomagnetic circuit breakers open, just close a volt-free contact in the remote
activation terminals. The contact must be able to work with 230 Vac 50 Hz and a power of 40 VA.
The remote activation terminals are placed in cubicle D (AC module), next to terminal 220.
