Start-Up; Checking And Measurement - Ingecon Sun 250 M220 Indoor Installation Manual

Ingeteam
The tasks outlined for this step must be carried out with the unit door always closed, thus avoiding possible contact
with live parts without IP2X protection.

6.2.1. Start-up

check that the inverter switches on and that no LeD error lights are on except for the manual shutdown light. next,
check that the variables on the monitoring menu are consistent; in particular the Vac Vdc levels.
The Vdc reading shows the voltage of the PV array at any given moment.
It allows you to check that the PV array is balanced. To do this, click "OK" on the Vdc display screen and confirm that
the displayed PVP and PVn values (indicating the voltage of each PV array pole to ground) are similar.
Finally, check that the inverter only displays the manual stop alarm (Alarm 1000H) on the monitoring menu.
Once the tasks described above are performed, you may proceed to start the inverter. Failure to comply with the veri-
fication tasks described above releases Ingeteam from any liability for possible damage to the system or the inverter
itself caused by such failure.
Proceed to start the inverter.

6.2.2. checking and measurement

Once connected to the unit network, the LeD "Start" is lit, verify that no error LeD display is on.
check that the monitoring menu parameters are consistent:
• The voltage of the PV array should be between 400 and 1000 Vdc and must remain balanced (similar PVn
and PVP).
• Vac tension shown on the display must fall within operating ranges.
• The RMS value of currents Iac1, Iac2 and Iac3 displayed should be similar.
• There are no alarms in the inverter (0000H).
It is always advisable to check the waveform of the current generated in the three phases using an ammeter clamp.
use the PPe listed in the "Personal Protective equipment" section (working with voltage) to get this reading.
