Important note:
in case of IT system, the power management function cannot be
performed. This is due to the fact that the meter does not support IT grid configurations.
In IT systems, the charger can therefore be used in the standard mode, with no power
management function.

1-phase meter configuration
The 1-phase meter configuration is performed through its ModBus interface.
In alternative the meter can be configured by means of its frontal button:
•
switch the device on simply connecting it to the 1-phase power supply
•
push the frontal button for at least 5 s
•
during this time the display values rotate in a fast sequence
•
release the button
•
wait for the protocol indication to appear (“ModBus should appear)
•
push the button once: the display shows the serial interface parameters. Select 8n1 = 8
bits, no parity, 1 stop bit
•
wait for the new display indication (the ModBus address), this happens automatically,
no needed actions
