2. Connect teamwork and monitoring communications cables.
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.

switch is required) or a third-party NMS as the monitoring system.

by group. For example, if the number of units under teamwork is 18, they can be divided
into two groups, for example, 9+9, 16+2, or 10+8.

It takes 3 x n seconds to collect data from n units. If the
time required for the host to collect data from all units
does not meet the performance requirements, group the
units.
• If units are not grouped (n = 1), set RS485
monitoring grouping to Enable on the Modbus
Settings screen for each unit.
• If units are grouped (n > 1; recommended: n ≤ 4), set
RS485 monitoring grouping to Enable on the
Modbus Settings screen for the unit with the COM/FE
port connected. Retain the default setting (Disable)
for other units.
