● If the SmartLi needs to connect to the ECC800-Pro, connect the ECC800-Pro to
the FE port on the monitoring interface unit of the SmartLi through the PoE
port of a smart ETH gateway.
● If the SmartLi needs to connect to a third-party network management device:
– If the communications protocol is Modbus-RTU, connect the third-party
network management device to the RS485 port on the monitoring
interface unit of the SmartLi.
– If the communications protocol is Modbus-TCP, connect the third-party
network management device to the FE port on the monitoring interface
unit of the SmartLi.
● When reinstalling the communications cable box, prevent the cable box from pressing
the cables.
● RS485 cables and FE cables must be shielded cables.
● Do not bind communications cables and power cables together.

You are advised to place lithium battery cabinets and connect parallel cables in
the sequence shown in the gure to avoid inconsistency between the actual
number of a lithium battery cabinet and the number displayed on its monitoring
screen. If the number displayed on the monitoring screen of a lithium battery
cabinet is
N
and its PARALLEL1 port is connected to the PARALLEL2 port of
another lithium battery cabinet, the number displayed on the monitoring screen of
the latter lithium battery cabinet is
N
+1.
