Eaton Corporation Page 46 Ver 1.1iv. Use multi-meter to confirm the total input power of PV strings in orderto ensure the input power from PV string will not be exceed thepermission setting 600VDC as the maximum operating voltageaccording to electrical specification of PV inverter and the maximumDC input current should be within 20A to each pole of DC terminal.IMPORTANTConfiguration of the PV modules should be done by qualifiedservice personnel with the instructions that are provided from themanufacturer of the PV modules.Ensure the configuration for each string of the PV-system meets thespecifications required by the Eaton grid-tied PV Inverter.Multi-MeterIt is important to use a multi-meter to measure the DC input voltagethat is generated from the PV modules which must not exceed600VDC.IMPORTANTThe Eaton grid-tied PV Inverter is designed with a transformer lesstopography. It is not recommended to connect with the PV modulesthat require positive (+) or negative (-) polarity to ground.And it is also necessary to have a circuited breaker or fuse switchinstalled between PV modules and PV Inverter. When there is PV stringconnected with the circuited breaker or fuse switch, please ensure to turnit off in order to prepare connect the DC cables to the DC input terminal ofPV inverter.B) For the DC cables, the terminal connectors is recommended to be usedwith cables in order to ensure the quality of conducting between DCcables and DC terminal is good as shown in figure 7.1.2.Figure 7.1.3: Terminal connectors are required for DC Cables
