NOTICE
To prevent damage to the PCB, it is NOT allowed to
connect the electrical wiring with the connectors already
connected to the PCB. First connect the wiring to the
connectors, then connect the connectors to the PCB.

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.

Solar inverter/energy management system
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 the installer reference guide.
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).
The rest of the wiring to X1A differs depending on the digital outputs
available on the solar inverter/energy management system and/or on
the Smart Grid operation modes that you want the system to run in.
