1. 3 WIRE CRIMP IF HIGH INST TRIP MODULE IS SUPPLIED.
2. ALL AUX. SWITCH CONTACTS SHOWN WITH BREAKER IN OPEN POSITION
AND WITH TRIP UNIT IN "NON-TRIPPED" STATE (OTS SWITCHES).
3. THE "SR" DEVICE HAS ADDITIONAL CIRCUITRY THAT PROVIDES A 0.5
SECOND SIGNAL PULSE FOR CLOSING OPERATION. POWER MUST BE
REMOVED AND THEN REAPPLIED FOR A SUBSEQUENT OPERATION.
4. TO PROVIDE SELECTED TIME DELAYS FOR SHORT TIME AND/OR GROUND
TIME FUNCTIONS FOR TESTING OR NON-ZONE INTERLOCKING APPLICATIONS,
A JUMPER FROM B-8 TO B-9 IS REQUIRED.
5. ON THREE POLE BREAKERS ONLY, HAVING GROUND FAULT FUNCTIONALITY,
A JUMPER INSTALLED FROM B-6 TO B-7 WILL ENABLE SOURCE GROUND
FAULT SENSING AND DISABLE RESIDUAL GROUND FAULT SENSING. INPUTS
B-4 AND B-5 WILL BE REASSIGNED FOR SOURCE GROUND SENSOR INPUTS.
6. NORMALLY OPEN CONTACT PROGRAMMED AS RELAY A, VIA DIGITRIP FRONT PANEL.
7. NORMALLY CLOSED CONTACT PROGRAMMED AS RELAY B, VIA DIGITRIP FRONT PANEL.
8. NORMALLY OPEN CONTACT PROGRAMMED AS RELAY C, VIA DIGITRIP FRONT PANEL.
