Update transport started

The inverter has successfully started the update.

27332

Update transport successful

The update file has been successfully transferred to the communication compo-
nent.

29001

Inst. code valid

The entered Grid Guard code is valid. Protected parameters have now been
unlocked and you can adjust the parameters. The parameters will be automati-
cally locked again after ten feed-in hours.

Checking the PV System for Ground Faults

If the inverter displays the event numbers 

3501

3601

 or 

3701

, there could be a ground fault. The

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

Danger to life due to electric shock

In the event of a ground fault, high voltages can be present.

• 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.

Destruction of the measuring device due to overvoltage

• Only use measuring devices with a DC input voltage range of 600 V or higher.

Procedure:

In order to check the PV system for ground faults, perform the following actions in the prescribed
order. The exact procedure is described in the following sections.

• Check the PV system for ground faults by measuring the voltage.
• If the voltage measurement was not successful, check the PV system via insulation resistance

measurement for ground faults.

Test by Measuring the Voltage

Proceed as follows to check each string in the PV system for ground faults.
