NOTES:
1. Excitation enabled when switch (S3) is open and disabled when switch is closed.
2. SPDT spring return to center-OFF position type switch (S1) for remote set point adjust.
3. J1-10 (DROOP_OFF) and J1-9 (VAR/PF_OFF) (if DVR2000EC+) are shorted to J1-4 (CGND) to
disable droop and VAR/PF control modes.
4. Normally-open contact closes in a fault condition.
5. Analog signal input when Auxiliary is configured for control or metering.
6. Should be shorted when Auxiliary is configured for 4-20 mA control or metering.
7. Sensing potential transformer is required if generator output voltage exceeds 600 Volts.
8. Phase B current transformer (CT-B) secondary may be connected to either quick-connect
terminals CT1 and CT2 or J2-2 and J2-11.
9. 120 ohm 0.25 watt resistor required if DVR is a terminal device on CAN backbone.
10. S1, S3 and transfomers supplied by others.
