For a 480Y/277V 3P4W load:
- 480Y/277V 3P4W load has 277V between each phase to neutral. Please select 4-Wire wye service type and enter 277V for expected voltage.
-
In the Web Portal (Power Meter Data Manager): Setup > Voltage Input > click the voltage input selection dot (Vin 1 or Vin 2)
- In the Expected voltage on L1 (VAC) field enter 277. [Note: this is the voltage between L1 or A phase to neutral.] In the Service type drop down menu select 4-Wire wye, voltage scalar to keep it as 1 (default), and Service correction keep default (no correction or switch left)
- Click SAVE and then click UPLOAD TO METER to complete the voltage input setup
For a 208Y/120 3P4W load (208V or 120V):
Similar to previous answer. Select 2-Wire wye service type and enter 120V for expected voltage.
