3Device Installation
Dimensions Space
Wall-Mounted Installation
•Install the SmartLogger and SmartModule on a flat and secure interior wall.
•When wall-mounting the SmartLogger and SmartModule, ensure that the cable connection area
faces downward for ease of cable connection and maintenance.
•You are advised to use the delivered tapping screws and expansion tubes.
1. Connect the SmartLogger to the SmartModule using a connecting plate.
If the SmartLogger
and SmartModule
have been
combined before
delivery, skip this
step.

2. Install the SmartLogger and SmartModule.
Guide Rail-Mounted Installation (Stand-alone)
•Before installation, prepare a standard 35 mm guide rail and secure it.
•The recommended effective length of the guide rail is 360 mm or greater.
•Ensure that the SIM card slot on the SmartLogger is not blocked.

4
Guide Rail-Mounted Installation (Combined)
•Before installation, prepare a standard 35 mm guide rail and secure it.
•The recommended effective length of the guide rail is 360 mm or greater.
•Ensure that the SIM card slot on the SmartLogger is not blocked.
1. Connect the SmartLogger to the SmartModule using a connecting plate.
2. Install the SmartLogger and SmartModule.
If the SmartLogger and
SmartModule have been
combined before delivery,
you only need to remove
the mounting ears and
guide rail clamps in the
middle. You do not need
to use a connecting plate
to connect the
SmartLogger and
SmartModule.

•Connect cables in accordance with the installation laws and regulations of the country or region
where the project is located.
•Before connecting cables to ports, leave enough slack to reduce the tension on the cables and
prevent poor cable connections.
Connecting the PE Cable
4.2
•To enhance the
corrosion resistance of
the ground terminal,
you are advised to
apply silica gel or paint
on it after connecting
the ground cable.
•If the SmartLogger is
connected to the
SmartModule over a
connecting plate,
connect a PE cable to
the ground point of the
SmartLogger or
SmartModule based on
site requirements.

Connecting the Ethernet Cable
4.3
•The SmartModule can be connected to the SmartLogger and a PC over the GE port.
•Connect the LAN port on the SmartLogger to one GE port on the SmartModule using an
Ethernet cable.
•If the delivered network cable is too short, you are advised to prepare a network cable of Cat 5e
or higher specifications and shielded RJ45 connectors. It is recommended that the cable length
be less than or equal to 100 m. When crimping the network cable, ensure that the shielding
layer of the cable is securely connected to the metal shell of the RJ45 connectors.

Connecting the 12 V Input Power Cable
4.4
The SmartLogger connects to the power supply over the 12 V input power port, and the 24 V input
power port of the SmartLogger functions as the 12 V output power port to supply power to the
SmartModule.

•It is recommended that the RS485 communication distance be less than or equal to 1000 m.
•The SmartModule can connect to RS485 communications devices, such as a solar inverter, an
environmental monitoring instrument (EMI), and a power meter over the COM port.
•Ensure that the RS485+ and RS485–terminals are respectively connected to the COM+ and
COM–ports on the SmartModule.
Cascading Connection
•You are advised to connect fewer than 30 devices to each RS485 route.
•The baud rate, communications protocol, and parity mode of all devices on the RS485
cascading link must be the same as those of the COM ports on the SmartModule.
