5.5.2. Steps for connecting the CT to the ESM1
90D24 EQX2 meter.
In order for the meter to read the current that circulates through
the installation, the transformer (CT) must be connected in the di-
rection indicated by the arrow inside the housing: from the loads
to the grid. Install it at the same point where the voltage is read.

5.5.3. Steps for the connection of
communications between meter
and inverter.
The communications cable required for connection to the meter is
connected to the inverter at the factory. It is identified as METER.
If you have accidentally disconnected it or need to connect
a longer one, etc., unscrew the protective casing, pass it through
the left cable gland that is labelled METER and connect it to the
RJ45 port labelled with the same name.

Connect the other end of the cable to the RJ45-2 port on the
meter as follows:
