The external meter is
connected to the charger
through an RS-485 bus.
The RS-485 terminal blocks
can be reached removing the
charger cover and then by
removing the inner cover
which protects the supply
terminal blocks.
The RS-485 wires are
connected to the bus
connector (terminal block) on
the charger as presented in
the picture.
The RS-485 signals from the
meter shall be connected as in
the picture where
• RS-485 positive signal “+”
is in “red”
• RS-485 negative signal “-“
is in “black”
After the external meter is
connected, the charger must
be closed again with its covers.
