Connecting the PE Cable

Note: To enhance the corrosion resistance of the ground terminal, apply silica gel or paint on it after connecting the PE cable.

Connecting the RS485 Communications Cable
NOTE

• It is recommended that the RS485 communication distance be less than or equal to 1000 m.
• The SmartLogger 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+ andCOM– ports on the SmartLogger.

COM1, COM2, COM3

| +| RS485A, RS485 differential signal+
–| RS485B, RS485 differential signal–

Cascading Connection

NOTE

• 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 SmartLogger.

Connecting the MBUS Cable
NOTE

• Ensure that both the solar inverter and SmartLogger support MBUS communication.
• If the SmartLogger is connected to the solar inverter through an AC power cable, no RS485 communications cable needs to be connected.
• If the SmartLogger communicates through MBUS, a miniature circuit breaker (MCB) or knife fuse switch needs to be installed to prevent device damage in the case of short circuits.

MBUS Networking

Connecting the DI Signal Cable
NOTE

• The SmartLogger 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 delivered network cable is too short, you are advised to prepare a network cable of Cat 5e or higher specifications and shielded RJ45 connectors. The recommended communication distance is 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 Optical Jumper
NOTE

• The SmartLogger can connect to devices such as the access terminal box through optical fibers.
• Optical modules are optional. Configure the 100M or 1000M optical module based on the peer port on the optical switch. The optical module should use the SFP or eSFP encapsulation.
• The transmission distance supported by the 100M optical module should be greater than or equal to 12 km, and the transmission distance supported by the 1000M optical module should be greater than or equal to 10 km.
• When inserting an optical module into the SFP1 port, verify that the side with a label faces upward. When inserting an optical module into the SFP2 port, verify that the side with a label faces downward.
  • Insert the optical module into the SFP1 or SFP2 port. If there are two modules, insert one into each port.
