• SPEED2 MOTOR SOURCE: This setting selects source for a motor protection when two-speed motor functionality is
used. This can be separate voltage and current banks or one voltage and current bank one with different full load cur-
rent value at the second speed (entered in the SPEED2 MOTOR FLA setting). If separate CTs with different ratios or sec-
ondary currents are required for speed 2, then the relay should be ordered with two CT banks.
• SPEED2 MOTOR FLA: This setting specifies the motor full load current for speed 2.
