Eastron SDM230 V2 cable to connect to Growatt SPH5000

[8BYxzuQ9DjbeKu3X]

I have just installed a Eastron SDM230 V2 meter and I now want to connect it to my Growatt SPH5000 Inverter but I cannot find the spec for the cable I need to connect it.

Does anyone know what pins need to be connected and which socket it should be plugged into in the Inverter, the Growatt manual does not give any real detail but it looks as though it should plug into the same place that the CT clamp is using.

Thanks
