Setpoint Behavior Default Units
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.
OFF N/A
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.
