NOTES: Check the box adjacent to the switch settings you have chosen. For additional refer-
ence, shade in the corresponding DIP switch positions.
* 59N and 27N functions respond to fundamental frequency component of input waveform only,
regardless of the position of switch 8.
** When 69.3 V is chosen for the VT secondary voltage, 69.3 V is internally converted to 120 V
(1 pu) for all calculations and for setting and display purposes.
† If line-to-line is chosen for the basic VT inputs (DIP switch 5 is ON), reverse power sensing
will respond to total three-phase power regardless of the setting of DIP switch 4.
†† If the system frequency selection (DIP switch 7) is changed from the original factory calibra-
tion, the unit must be recalibrated (see the self-calibration procedure in Chapter 7, Test
Procedures).
