1.2 Precautions for Use
Warning
Do not drive with the front cover open.
The power switch and PCB are exposed, and can cause electric shock.
Do not operate the switch with wet hands.
It may cause electric shock.
Do not open the front cover except for regular checks, even if the power is not on.
Even if power is lost, the internal PCB in the terminal may be charged, causing an electric
shock.
When performing wiring or routine checks, turn off the power and check that the input
power of the terminal is discharged with measuring equipment such as Multi-Tester (VOM)
after 5 minutes.
The high voltage may be charged to the PCB inside the terminal, causing electric shock.
Do not use the wire when it is damaged.
It may cause electric shock.
Do not place heavy objects on the wire.
Damage to the wire sheath can cause electric shock.
Do not input power even if installation is complete on terminals with damaged parts.
It may cause electric shock.
Caution
Do not install near flammable materials.
Installation on or near flammable materials may cause fire.
In case of terminal failure, disconnect the terminal input power.
Failure to do so may result in a fire caused by a secondary accident.
Do not turn on the power even if the installation is complete on devices with damaged
products.
It can cause electric shock and bring damage to additional parts.
Do not allow foreign substances such as screws, metal substances, water or oil to enter the
terminal.
It may cause fire.

2. Product Overview
2.1 Basics
Soleaf Air receives information from solar inverter, sensor box for weather observation, and
system interface and sends information to the server so that power generation corporations can
monitor solar power generation facilities remotely. Please familiarize yourself with this manual
before installing or using the product.
It can be connected to a solar inverter and, when connecting the device, it must be connected
to the communication port specified for that device with the RS485 interface. Device information
collected from the Soleaf Air can be sent to a web server or local server via the RS485 interface to
monitor solar energy integrated generation information in real time or to retrieve historical
information stored on the server.
Plant information and account information required for server account setup and Soleaf Air
setting are generated and managed by the monitoring maintenance specialist. Contact your
monitoring maintenance specialist to learn how to install, connect, and monitor your monitoring
device, and access the server.

3. Installation
3.1 Transportation
Please transport by proper means according to product weight.
Please check external conditions.
Do not pile up beyond the limited level or height.
Do not open the cover while being transported.
Do not drop or cause damage with shock

10
3.2 Installation Location
Install it in a location that meets the following conditions:
To prevent life or performance degradation, install Soleaf Air in a location that does not
receive direct sunlight.
Do not install it in a place with vibration.
As the lifetime of the product is greatly affected by ambient temperature, do not allow the
ambient temperature of the installation site to exceed the allowable temperature (20°C to
50°C).
Avoid hot and humid places (relative humidity is below 90% and there should be no dew
formation).
Avoid locations with oil mist, flammable gas, fiber dust, dust and moisture.
Install at the place where no salt exists.
Install in a location where the Wi-Fi signal is highly sensitive. Poor Wi-Fi signal sensitivity will
prevent smooth communication. (Check sensitivity using Wi-Fi sensitivity measurement
application.)
Avoid places with low signal sensitivity, such as walls or enclosures.
3.3 Installation Precautions
lFollow the instructions in this operation and installation manual.
lThis product may be installed indoors and outdoors.
lBe careful not to install in a wet, dusty, direct ray of sun light or high temperature location.
lWhen installing outdoors, make sure that there is at least one meter of space from the
ground.
lDo not place any heavy items on the product.
lDo not spray or place flammable substances on this product.
lInstallation direction must be set followed by the guidelines in this manual.
lDo not drop or cause damage with shock.

11
3.4 Installation Precautions
Please refer to the diagram below for installation.
Figure 6. Soleaf Air Installation Method
1) Drive a hole in the wall to attach at a vertical 45mm gap of 2 points the CAD block nut to be
tightened with the collar. The enclosed CAD block nut specification is M4*35. (see Figure 2)
2) Insert the nut into the machined hole and attach it firmly using a tool such as a hammer.
3) Attach the bolt to the attached nut.
Here, do not fully attach but remain 3 to 4 mm from the wall (see Figure 1).
4) Attach the product to the bolt and press lightly in vertical downward direction to fix it. (See Figures
2-3)
5) If the product is loosely attached or difficult to attach, retry by adjusting the screw spacing. (See
Figure 1)

3.5 Precautions for Wiring
Figure 7. Antenna and Power Cord Composition
For safety, be sure to check that power is off when connecting power
lines!
Connect the inverter connector to the top connector of the Soleaf Air.
Pay attention to the separation of power and ground wires when connecting the AC connector.
The Soleaf Air uses a 5V power source inside the inverter for power. If it is not properly connected,
the wires must be carefully routed as this may malfunction or damage the Soleaf Air. Connect the
inverter, system connection board RS485 connector, to fit the hole.
lInstall the Soleaf air before wiring (connector connection).
lTurn on the inverter power to the 'ON' state after the wiring is complete and before closing the
cover.
lWhen the cover is closed and powered on, the Soleaf Air is powered on.
Do not open the cover or disconnect the connector while it is operating.

13
For safety, be sure to check that power is off when connecting power
lines!
lAC Power Line Connections
Connect the power line to the lower input of the cut-off switch by processing the wires or
terminals. Connect one line to one terminal without dividing the polarity of the line. Do not
connect the ground wire.
lSerial Connection Termination Resistance Processing
lWhen connecting the S ㅐleaf Air to multiple units (up to three units), the communication line
must be terminated to ensure smooth serial communication. As communication between devices
may be abnormal if the termination resistance is not handled or handled incorrectly, to enable
termination resistance on the appropriate device referring to the diagram below. Since the serial
communication termination resistance process may vary by inverter models, refer to the
corresponding inverter manual for details on how to set it up. If more than four inverters are
connected to the Soleaf Air, communication will not take place. Check the quantity of inverter
that can be connected.
(Termination Resistance ON) (OFF) (OFF)

lThe 'Power Status Indicator' lights up when the Soleaf Air is powered on. The 'PWR Status
Indicator', 'STA Status Indicator', and 'LNK Status Indicator' remain lighted when power is
connected. If the 'PWR Status Indicator', 'STA Status Indicator', and 'LNK Status Indicator' flash or
turn off, check for basic status such as whether there is a connection between the Soleaf Air and
the inverter, etc.
lIf the 'Power Status Indicator' is off, make sure that the inverter that supplies power to the Soleaf
Air is not turned off. If the external switch and power supply are proper functioning, the Soleaf air
internal switch may be switched off. In this case, contact your monitoring maintenance specialist.
lIf the 'STA Status Indicator' flashes, it may not be connected to the inverter. Even if the inverter
stops operating at night, the indicator may flash. Check that the Soleaf Air is properly connected to
the inverter and if there is any problem, contact the inverter maintenance specialist.
lIf the 'LNK Status Indicator' flashes, the Wi-Fi network may be disconnected. Make sure that the Wi-
Fi signal strength and the sharing device you use are not turned off, and that Internet service is
provided normally. If there are no problems with peripheral devices, contact your monitoring
specialist.
