4.14.4.3 Connecting the Teamwork Network Cable
● Units of different models and software versions cannot be networked for
teamwork.
● Select a monitoring cable connection mode based on the protocol supported by
the NMS.
●
●
● The teamwork modes include FE teamwork and CAN teamwork. FE teamwork
is recommended. FE teamwork support point-to-point communication, long-
distance cascading, and group upgrade. If the number of units in a group is
greater than 16, FE teamwork needs to be implemented by group. The total
length of CAN teamwork cables should be less than or equal to 310 m.
Otherwise, the communication quality will be affected.
● The teamwork communications cables should be CAT 5e or higher shielded
network cables (cable impedance ≤ 10 m/ohm). Shielded metal RJ45
connectors should be used. The shield layer of the network cables should be
reliably connected to the shield layer of the RJ45 connectors to ensure that the
shield layers are properly grounded; otherwise, the teamwork networking of
the units may fail. If the RJ45 connectors are of poor quality or are not properly
crimped, the communication may be abnormal. Use a standard crimping tool
to crimp the RJ45 connectors onsite.
● The length of the network cable between adjacent units should be less than or
equal to 100 m. Route cables in compliance with local standards. Take
appropriate shielding measures, such as using a galvanized pipe or an ELV
cable tray, to reduce the impact of electromagnetic interference on teamwork
communication.

If the NMS supports the Modbus-RTU protocol, select RS485 monitoring.
If the NMS supports Modbus-TCP/SNMP, select FE monitoring.
