3.4 Choose an installation location
Choose an appropriate location and install Ai-Logger to ensure that Ai-Logger can work
normally and efficiently.
Please take the following into consideration when selecting an installation location.
1. Ai-Logger is rated IP20, do not place Ai-Logger outdoors.
2. Do not place the Ai-Logger in an easily accessible environment to avoid damage to the
Ai-Logger.
3. The ambient temperature should be kept at -20℃~+60℃, and avoid direct sunlight.
4. The ambient humidity of the installation location cannot exceed 95%. Excessive
humidity may cause damage to internal components.
5. Ensure that the RS485 communication distance does not exceed 1000m, and the
Ethernet communication distance does not exceed 100m.
6. It is recommended to install the Ai-Logger at an appropriate height.
7. Do not turn Ai-Logger upside down. When the cooling holes are facing upward, dust
might fall in and affect the life of the Ai-Logger.
8. The installation method and location must be suitable for the weight and size of the Ai-
Logger.
9. Make sure the cable connection area is facing down when mounting on walls or rails.

UM0033_Ai-Logger_EN_V02_0123 9
10. The distance between Ai-Logger and surrounding objects should meet the following
conditions: the distance between the two sides is ≥500mm; the distance from the top is
≥500mm; the distance from the ground is ≥1500mm, as shown in the figure.
3.5 Install Ai-Logger
There are three installation methods for the Ai-Logger: desktop installation, wall-mounted
installation, and rail installation.
3.5.1 Desktop installation
How to install Ai-Logger on desktop
●First install the antenna by screwing clockwise in the thread on Ai-Logger, the
antenna can be bent 90°and rotated 360°after installation.

10 UM0033_Ai-Logger_EN_V02_0123
Steps
Step 1: Take the Ai-Logger out of the outer packaging.
Step 2: Place the Ai-Logger on a horizontal table.
3.5.2 Wall-mounted installation
How to mount the Ai-Logger on the wall.
1. Install Ai-Logger on a solid and flat wall and make sure Ai-Logger is steadily fixed to the
wall.
Measure out the following dimensions on the wall and mark them well. Ai-Logger can
be hung on the wall with three screws to make it more steady, or it can be hung on the
wall with only two screws on the top.
Notice
●Please choose horizontal desktop to install Ai-Logger to avoid damage caused by Ai-
Logger sliding down.
●Do not place the Ai-Logger in a place where it is easy to touch the cable to avoid
signal interruption.
Notice
●Secure the Ai-Logger through the wall mounting holes on the back (as shown in the
figure below).

UM0033_Ai-Logger_EN_V02_0123 11
2. Use a pistol drill (φ6 drill bit is recommended) at the marked place to drill a depth of 24-
25mm. Clean up the debris in the hole, then install the expansion coil and screw on the
wall. The screw requirements are as follows. The thickness of the head is 2mm, and the
diameter is φ6-10. Finally, hang the Ai-Logger on the screw.
3.5.3 Rail installation
1. Choose a standard DIN35mm rail with a thickness of 1mm and a rail length of not less
than 280mm.
2. Fix the guide rail to the selected cabinet or wall. The way of fixing on the wall is similar
to wall mounting.
3. Mount the Ai-Logger on the rail.
There are two ways to install:
Method 1:
Align the Ai-Logger rail groove with the rail and push it into place.

12 UM0033_Ai-Logger_EN_V02_0123
Method 2:
Hold the Ai-Logger to clamp the upper grove on the upper edge of the rail, rotate the Ai-
Logger to make the rail contact the two rail clips on the Ai-Logger, then press the Ai-Logger
to make the rail completely snap into the rail clips. If it is difficult to snap into place, use a
flat-blade screwdriver and gently move the clip down through the hole, then the rail can be
easily snapped into place.
4. Fix the end brackets on the rail at both ends to prevent the Ai-Logger from moving on
the rail.
5. Check to make sure the Ai-Logger is securely installed.

4.2.2 Connect to multiple inverters
How to connect Ai-Logger with multiple inverters
Ai-Logger can be connected to multiple inverters at the same time by daisy chain, as shown
in the figure
Note
⚫A single Ai-Logger supports up to 80 devices, and it is recommended that the
number of devices connected to each RS485 channel be less than 30.
⚫The addresses of all devices on each daisy chain must be within the address range
set by Ai-Logger, and there must be no duplication, otherwise the communication
will fail.
⚫If Ai-logger detects a conflict between the RS485 addresses of the inverter, it will
reassign a different address without the need of going to the inverter to modify it.
⚫All devices on each daisy chain must have baud rates set to 9600.
⚫It is recommended to use a CAT 6E network cable with a cross-sectional area of
0.5mm² or more or a shielded twisted pair cable of 1mm²

Connect to a weather station
4.3 Connect to a smart meter
How to connect the Ai-Logger to a smart meter
Background information: Ai-Logger can connect to smart meters that support standard
MODBUS-RTU protocol or DL/T645 protocol.
------End
4.4 Connect through Ethernet cable
Background information: Ai-Logger can be connected to Ethernet switches, routers and
other devices through Ethernet cable, and can also be connected to the Ethernet electrical
port of a PC directly or through a Hub. You can select the device to be connected according
to the specific networking scenario.
Steps
Step 1. Insert one end of the purchased network cable into the Ethernet port of the device.
Note
⚫Ai-Logger only supports weather stations with standard MODBUS-RTU protocol. One
Ai-Logger can only manage one weather station.
⚫For the definition of the RS485 communication cable of the weather station, please
refer to the operating instructions delivered with the weather station for details.
Note
⚫After the MODBUS-RTU protocol smart meter is wired, you need to log in to the
embedded WEB and set the relevant parameters of the MODBUS smart meter. For
details, please refer to 6.4.5.2 Setting smart meter parameters.
⚫The smart meter does not support automatic identification, you need to set the
relevant parameters of the MODBUS smart meter through the embedded WEB,
please refer to 6.4.5.2 Setting smart meter parameters for details.
⚫The protocols supported by the devices connected to a COM port of the Ai-Logger
should be the same. After completing the wiring, you need to modify the protocol of
the corresponding COM port through the embedded WEB. For details, please refer
to 6.5.2.2 Setting RS485 parameters.
⚫The smart meter does not support automatic identification and needs to be added
manually through the embedded WEB. For details, please refer to 6.4.5.2 Setting
smart meter parameters.

Step 2. Plug the other end of the network cable into the "LAN" port of the Ai-Logger.
------End
4.5 Connect to Ripple Control Receiver
How to connect Ai-Logger to Ripple Control Receiver.
Background information: In Germany and parts of Europe, grid companies use Ripple
Control Receiver to convert grid dispatch signals to dry contact and need power plants to
receive grid dispatch signals using dry contact communication.

Note
⚫Pay attention when preparing your own network cable:
⚫Use CAT 5E or higher shielded network cables.
⚫It is recommended that the cable length should not exceed 100 meters.
Note
⚫Ai-Logger provides AP hotspot as distribution network
⚫If Ai-Logger is connected to PC directly or through Hub, both IP addresses need to
be set in the same network segment.
⚫If the Ai-Logger needs to be connected to the PC through a network device (such as
a router), the IP addresses of the Ai-Logger and the router and other network devices
need to be set in the same network segment. Please set the gateway of Ai-Logger
correctly to ensure that it can communicate with network devices.

When Ai-Logger is connected with Ripple Control Receiver, the connection method is as
shown in the figure
Steps
Step 1: Choose a cable of suitable length and connect one end to the Ripple Control
Receiver.
Step 2: Connect the other end of the cable to the DI port of the Ai-Logger.
-----End
Notice
⚫When supporting active power remote control and reactive power remote control at
the same time, only one of the four outputs of the two Ripple Control Receivers can
be in a closed state.
Notice
⚫In order to use the power grid dispatch function normally, after the cable is
connected, you need to set up relevant settings (active power schedule or reactive
power schedule) on the embedded WEB. For details, please refer to 7. Grid dispatch.
