Determine the DC voltage between:– protective earth (PE) and the positive cable of the PV generator– protective earth (PE) and the negative cable of the PV generator.If stable voltages can be measured, there is a ground fault in the DC generator or its wiring. The ratio between themeasured voltages gives an indication as to the location of this fault.2. Rectify any faults before taking further measurements.3. Determine the electrical resistance between:– protective earth (PE) and the positive cable of the PV generator– protective earth (PE) and the negative cable of the PV generator.In addition, ensure that the PV generator has a total insulation resistance of more than 2.0 MOhm, since theinverter will not feed in if the insulation resistance is too low.4. Rectify any faults before connecting the DC generator.NOTEThe threshold value from which the insulation monitor reports an error can be set in the “Parameters”menu.7.3.3 Designing the PV generatorNOTEIn accordance with IEC 61730 Class A, connected PV modules must be dimensioned for the DC systemvoltage provided, and at least for the value of the AC grid voltage.Pmax I rated. max MPP tracker I SC max MPP trackerMPP tracker <24 kW <20 A <32 A7.4 Connecting the PV generatorConnect the PV generator to the 4 DC positive and the 4 DC negative connection plugs on the underside of thehousing (see Figure 18 on page 21). Note the wiring examples given below. The inverter detects these typicalconfigurations automatically. In individual cases, you need to set the selected DC connection after installation in themenu.DANGERRisk of fatal injury due to contact voltages!Removing the plug connection before disconnecting the inverter from the PV generator may lead toinjuries and damage the unit.› During installation: Electrically disconnect the DC positive and DC negative from the protectiveearth (PE).› Remove the plug connector.CAUTIONDamage to the device in case of faulty configuration of the DC connector.A faulty configuration of the DC connector (polarity +/-) causes equipment damages in the DCconnection if it is connected permanently." Please check polarity (+/-) of the DC connector before connecting the DC generator" The DC voltage must not exceed 1000V at any time.
