7.5.2 Checking the PV generator for a ground fault
DANGER
Risk of fatal injury due to electric shock!
Severe injury or death will result if the live connections are touched. When there is sunlight present on the
PV generator, there is DC voltage on the open ends of the DC cables.
› Only touch the PV generator cables on the insulation. Do not touch the exposed ends of the cables.
› Avoid short circuits.
› Do not connect any strings with a ground fault to the device.
NOTE
The threshold value from which the insulation monitor reports an error can be set in the "Parameters"
menu.
