4.3 Commissioning
Context
●
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.
Procedure
Step 1 Set parameters for general input units on the ECC800-Pro WebUI.
1. Set parameters for general input unit 1.

Set this parameter to a
value consistent with
the information on the
nameplate of the
general input unit. For
example, if the model is
NMW-0250 AC, set
Rated system current
to 250 A.

parameter is
not displayed
for some
general input

250
Set based on actual
conditions.
For example, if Rated
system current is 250
A, set System CT ratio
to 250.
