. Adjust 08-23 to enable or disable the ground Fault (GF) protection
08-23 =0: Disable the ground Fault (GF) protection
= 1: Enable the ground Fault (GF) protection
. If the inverter leakage current closes to 50% of inverter rated current and the ground
failure function is enabled (08-23), the digital operator will display the failure message of
"GF Ground Fault" (GF), failure contact acts and the inverter will coast to stop.
