SEL RELAY INSTRUCTION MANUAL ADDENDUM
ACB PHASE ROTATION OPTION
The SEL relay instruction manuals are written for standard ABC phase rotation applications.
If your SEL relay is ordered with the ACB phase rotation option, references made in the
instruction manual to voltage and current phase angle should be noted accordingly. The
firmware identification number (FID) may be used to verify whether your relay was ordered
with ABC or ACB rotation.
All current and voltage inputs are connected to the SEL relay rear panel as shown in the
instruction manual.
