5.5. METER AND CT CONNECTION.
5.5.1. Steps for connecting the power of the ESM1
90D24 EQX2 meter.
The ESM1 90D24 EQX2 meter must be connected to the installa-
tion's connection so that it can read its voltage. Connect to holes 1
and 4 as indicated below:

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 direc-
tion 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.
