To Respond To A Ground Fault; Figure 5-9. Ground Fault Error Message - Advanced Energy AE 600 User Manual

WARNING:
For the GFDI circuit to function as designed, the solar array safety ground
must not be connected to the PV array positive or negative leads. Bonding
the safety ground to the grounded leg of the array anywhere but through the
inverter will cause the GFDI circuit to be bypassed. This would defeat the
operation of the GFDI and potentially create an unsafe operating condition.
AVERTISSEMENT:
Pour que le circuit GFDI fonctionne normalement, la prise de terre de
sécurité du système PV ne doit pas être branché aux câbles positifs ou
négatifs des piles PV. Brancher la prise de terre de sécurité au pied des piles
ou à toute autre partie que l'onduleur causerait une mise hors circuit du
GFDI. Ceci ne empêcherait le fonctionnement normale du circuit GFDI et
créerait des conditions de fonctionnement potentiellement dangereuses.
The GFDI functions using a 5 A fuse to connect or bond the solar array negative (or
the solar array positive, if using a positively grounded panel array) to earth ground.
If the ground fault current exceeds 5 A between the grounded array terminal and the
earth ground, the fuse will open and disconnect the solar panels from their ground
reference, interrupting the ground fault. In this situation, the inverter will cease
operation and display a ground fault message.

To Respond to a Ground Fault

• If the inverter displays a ground fault as shown in the following figure turn off
the AC and DC to the inverter and refer to the inverter maintenance and
troubleshooting information.
The following figure shows the inverter ground fault error message.
