•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.

•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.

Connecting the DI Signal Cable
4.6
•The SmartModule can receive DI signals such as remote power grid scheduling commands and
alarms over DI ports. It can only receive passive dry contact signals.
•It is recommended that the signal transmission distance be less than or equal to 10 m.

If the
Communication using expired certificate function is disabled for the
SmartLogger
and the digital certificate of the SmartModule becomes invalid,
after enabling the function, press the RST button for 3s to 10s to enable the
SmartModule
to enter the mode of ignoring digital certificate expiration and
restore the communication with the
SmartLogger. The alarm/maintenance
indicator (ALM) blinks red slowly.

SmartModule is reloaded through the
SmartLogger
, the SmartModule communication can recover.
Hold down the
button for more
than 60s.
Within 3 minutes after the
