INFORMATION
Mind the polarity of the cable. The positive wire MUST be connected to X2A/1; the
negative wire to X2A/2.
WARNING
Make sure to connect the electricity meter in the correct direction, so that it
measures the total energy injected INTO the grid.
INFORMATION
Before installation, confirm that the solar inverter/energy management system is
equipped with the digital outputs required to connect it to the LAN adapter. For
more information, see
Connector X1A is for the connection of the LAN adapter to the digital outputs of a
solar inverter/energy management system, and allows for the integration of the
heat pump system in a Smart Grid application.
X1A/N+L supply a 230 V AC detection voltage to the input contact of X1A. The
230 V AC detection voltage enables the detection of the state (open or close) of
the digital inputs and does NOT supply power to the rest of the LAN adapter PCB.
Make sure X1A/N+L are protected by a fast acting circuit breaker (rated current
100 mA~6 A, type B).
