5.5 Commissioning the New Main Way
Context

In the new main way 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.

380
Set based on actual
conditions.
Rated system
current
NOTE
This parameter is
not displayed for
some general
input units.
250
Set based on actual
conditions.
NOTE
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.
System CT ratio
NOTE
This parameter is
not displayed for
some general
input units.
250
Set based on actual
conditions.
For example, if Rated
system current is 250 A, set
System CT ratio to 250.
Upper load
current threshold
80
When the load current
exceeds the preset value, an
alarm is generated.
Lower load
current threshold
60
When the load current
exceeds the preset value, an
alarm is generated.
