12.3 Checking the PV System for Ground Faults

If the red LED is glowing and the event number 3501, 3601 or 3701 is being displayed in the

Results

menu on the inverter user interface, there may be a ground fault present. The electrical

insulation from the PV system to ground is defective or insufficient.

DANGER

Danger to life due to electric shock when touching live system components in
case of a ground fault

If a ground fault occurs, parts of the system may still be live. Touching live parts and cables
results in death or lethal injuries due to electric shock.

• Disconnect the product from voltage sources and make sure it cannot be reconnected

before working on the device.

• Touch the cables of the PV array on the insulation only.
• Do not touch any parts of the substructure or frame of the PV array.
• Do not connect PV strings with ground faults to the inverter.
• Ensure that no voltage is present and wait five minutes before touching any parts of the PV

system or the product.

NOTICE

Destruction of the measuring device due to overvoltage

• Only use measuring devices with a measurement range designed for the maximum AC and

DC voltage of the inverter.
