EMS System Setting Description
Nominal Voltage
Settings Verify the nominal input voltage and frequency settings are
correct for your installation. Adjust as needed.
NOTE Specify nominal voltage as Line to Neutral voltage (not
Line to Line voltage).
Input / Output CT
Settings Main input monitoring option only. Select the type and rating
for the input and neutral CTs installed (400A) and for the input
ground CT installed (100A).
NOTE Configure a CT only if it is installed.

its approximate values.
System Name and
Rating (1) Specify a Name for the system:
To change the default name, double−click in the Name field and
type the new name. Press Enter, then click Yes to confirm.
(2) Set the Rating in VA for the installation:
This setting matches the summation of the ratings on your
panels and is the overload level. To calculate the Rating, multiply
the main breaker rating for each panel by the nominal L−N
voltage. For example, for two 225A panels and a 120V nominal
input voltage, the rating is 225
2 120, or 54,000 VA.
NOTE If your breakers are configured, you can select Auto
Calc to have the software automatically calculate the VA rating.
