Page 19 �.� Connection of the ground line Good grounded is important for resist the surge voltage shock and improve EMI's performance. So before the connection of AC, DC, communication connections, inverter needs to ground ﬁrst. For a single system, just ground the PE cable; For multiple machine systems, all PE cables of the inverter need to be connected to the same grounding copper platoon to ensure the equipotent connection.
Page 20 Phone GPRS Router Web Server WIFI Pic �.�� Internet monitoring solution �.�.� Installation of datalogger When installing the WiFi stick, tear oﬀ the sealing strip on the inverter. Insert the datalogger into the interface and ﬁx it with a screw. The conﬁguration of the datalogger needs to be performed after various electrical connections have been completed and the inverter DC power on.
Page 21 �.�.� Conﬁguration of datalogger For the conﬁguration of datalogger, please refer to illustrations of the datalogger. �. Start up and Shut oﬀ Ensure that the inverter meets the following conditions before starting the inverter, otherwise it may cause ﬁre or damage to the inverter without quality assurance, at the same time the situation on our company does not undertake any responsibility.
Page 22 �. Zero-export function via energy meter There're four kinds of energy meters for this series inverter. First type is Eastron SDM��-Mod- bus V� which is able to measure the Max. ��A current directly. More details please refer to Pic �.� & �.�. For the Eastron SDM�� MCT ��mA, it needs external CT to measure the current. The CT power range is from �A-��A.
