DANGER:

Cette unité contient des dispositifs de stockage d'énergie qui prennent

jusqu'à 5 minutes pour se décharger. Vérifier que les condensateurs à haute

énergie sont complètement déchargés avant de travailler sur l'unité.

DANGER:

Verify that no shock hazard exists between both fuse terminals and earth

ground before removing the fuse. A 600 V rated fuse pulling device is

required.

DANGER:

Vérifier qu'il n'y a aucun risque d'électrocution entre les deux bornes de

fusible et la prise de terre avant de retirer le fusible. Un arrache-fusible d'une

capacité de 600 V est requis.

1. Open the control electronics compartment and locate the GFDI fuse on the

backplane PCB.

2. Inspect the 5 A GFDI fuse for continuity using a multimeter.

◦ If the fuse is not open, continue troubleshooting using the steps below.

◦ If the fuse is open, a ground fault exists outside the inverter. Refer to the

instructions for resolving an external ground fault.

3. Remove the GFDI fuse.

4. Check for continuity (ohms) across the GFDI fuse.

If the meter indicates no continuity then a ground fault likely exists.

◦ Check the DC voltage between the grounded terminal of the array and earth

ground. The voltage should be less than 30 volts with the GFDI fuse

removed. If the voltage is higher than 30 volts, a ground fault likely still

exists. Check the array wiring. For the best results, perform this test with the

DC disconnect in both the ON and OFF positions.

◦ Make sure the grounded leg of the solar array is not disconnected inside the

DC disconnect compartment.

5. Once the ground fault condition has been eliminated, verify the voltage

between earth ground and the grounded side of the PV array is less than 30

volts.

6. Ensure the DC disconnect is in the OFF position and install the new GFDI fuse.

7. Restart the inverter.
