Step 1 Set parameters for general input units on the ECC800-Pro WebUI.
1.
Issue 05 (2020-10-15)
The ECC800-Pro operation description is applicable to the software version
V100R003C00.
In the NMW scenario, general input units and power distribution units
communicate with the ECC800-Pro using the Modbus-MAC protocol.
After the general input units and power distribution units properly connect to
the ECC800-Pro, the ECC800-Pro automatically identifies the units.
Then, you need to set parameters for the general input units and power
distribution units; otherwise, a false alarm may be generated.
Set parameters for general input unit 1.
