•
CalOverride
Overrides CT calibration.
•
When set to OFF, the inverter detects the CTs number and direction of
CTs.
•
A value of ON assumes a specific orientation and direction of CTs.
•
CTTurnsRatio
Turns ratio of the CTs installed.
•
Default turns ratio of 1,500 is compatible with included clamp type CTs
•
If installation restriction requires larger accessory CTs, set point shall be
adjusted to 3,000. Verify turn ratio of CTs before modifying this setting.
