Page 18: The Connection Of The Ground Line
�.� The connection of the ground line Good grounding is good for resisting surge voltage shock and improving EMI performance.There- fore, before connecting AC, DC and communication cables, you need to ground the cable ﬁrstly. 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 equipoten- tial connection.

Page 22 7. Zero-export func�on via energy meter There're two 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.
