Step 2 Insert the H type tool and pull it out from the socket.
6.6 Grounding the inverter
The inverter must be connected to the AC grounding conductor of the power
distribution grid via the ground terminal (PE) .
Because of the transformerless design, the DC positive pole and DC
negative pole of PV arrays are not permitted to be grounded.
6.7 Active power control with smart meter , CT or ripple
control signal receiver
The position of export limitation CT or Meter must between the
Inverter & Load and gird.
This series inverter has integrated export limitation functionality. To use this function,
you can connect smart meter or CT. The smart meter model is Eastron
SDM120CT-M(40mA). The CT Model is ESC16-100 (ECHUN)/
CTF16-2K5-100(Shenke) .The primary aperture is 10mm,output cable length is 5m .
The arrow on the CT must pointing towards the inverter.The detailed information
about the Meter,please refer to Annex -Eastron SDM120CT-M(40mA) user manual.
