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.

To connect the solar inverter/energy management
system
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.
INFORMATION
How the digital inputs are connected to X1A depends on
the Smart Grid application. The connection described in
the instructions below is for the system to run in the
"Recommended
ON"
operation
mode.
For
more
information, see the installer reference guide.
WARNING
Make sure X1A/N+L are protected by a fast acting circuit
breaker (rated current 100 mA~6 A, type B).
WARNING
When connecting the wiring to LAN adapter terminal X1A,
make sure each wire is securely fastened to the
appropriate terminal. Use a screwdriver to open the wire
clamps. Make sure the bare copper wire is fully inserted
into the terminal (bare copper wire CANNOT be visible).

Provide a detection voltage to X1A/N+L. Make sure X1A/N+L
are protected by a fast acting circuit breaker (100 mA~6 A,
type B).

For the system to run in the "Recommended ON" operation
mode (Smart Grid application), connect the digital outputs of the
solar inverter/energy management system to LAN adapter
digital inputs X1A/1+2 LAN.
