SOCKET USED WITH DIGITRIP 520M GROUND ALARM POWER SUPPLY MODULE WILL "HANG UNCONNECTED" IF DIGITRIP 220 OR 520 IS SUPPLIED. 4. ALL CONTTS SHOWN WITH BREAKER IN OPEN POSITION AND WITH SPRING NOT CHARGED AND WITH TRIP UNIT IN "NON-TRIPPED" STATE (OTS SWITCHES). 5. THE SPRING RELEASE CESSORY CONSISTS OF A "SR" COIL AND A P.C. BOARD. THE PRINTED CIRCUIT PROVIDES A.20 SECOND PULSE FOR THE CLOSING OPERATION. VOLTAGE MUST BE REMOVED AND THEN REAPPLIED FOR SUBSEQUENT OPERATION. AN OPTIONAL LATCH CHECK SWITCH (LCS) CESSORY MAY BE CONNECTED TO THE SPRING RELEASE. THE (CLOSED) LCS DELAYS THE SPRING RELEASE PULSE UNTIL THE BREAKER MECHANISM IS READY TO CLOSE (CHARGED AND RESET). (THIS WILL INSURE THAT THE LATCH WILL ALWAYS BE IN THE PROPER STATE BEFORE THE SPRING RELEASE PULSE IS INITIATED.) IF VOLTAGE IS MAINTAINED TO THE SPRING RELEASE, THE CLOSING PULSE WILL OCCUR WHEN THE MECHANISM IS CHARGED AND RESET (LCS OPEN). VOLTAGE MUST BE REMOVED AND RE-APPLIED TO THE SPRING RELEASE FOR SUBSEQUENT OPERATION. 6. 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. 7. 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. 8. THIS LEAD SUPPLIED ON G62 STYLE HIGH INSTANTANEOUS TRIP MODULE ONLY. 9. MOTOR OPERATOR SWITCH SHOWN WITH BREAKER CLOSING SPRING DISCHARGED. 0. ON 4 POLE BREAKERS, THE NEUTRAL CURRENT SENSOR IS THE SAME STYLE AND WIRED THE SAME AS THE PHASE SENSORS AND IS LOCATED WITHIN THE BREAKER FRAME. THE SECONDARY CONTTS B-4, B-5, ARE NOT WIRED OUT.. SECOND SHUNT TRIP MAY BE INSTALLED (USING A-7,A-8 CONTTS) IN PLE OF UVR. THIRD AUX SWITCH NOT AVAILABLE WITH SECOND SHUNT TRIP. 2. ONLY ONE LATCH CHECK SWITCH MAY BE INSTALLED. USE OF CUSTOMER-CESSIBLE LATCH CHECK SWITCH (B-28,B-29,B-30) IN SERIES WITH SPRING RELEASE DEFEATS ANTI-PUMP FUNCTION AND IS NOT RECOMMENDED. SEE NOTE 5 FOR SPRING RELEASE LATCH CHECK SWITCH. 3. THESE CONTTS ARE PROVIDED FOR DIGITRIP 520MC AS STANDARD OR 520M AS OPTIONAL CESSORY. THE CONTTS ARE ASSIGNED FOR GROUND ALARM ON GROUND TRIP FUNCTION FOR LSIG TRIP STYLE. HOWEVER, FOR A LSI STYLE TRIP UNIT, THE CONTTS ARE ASSIGNED AS A HIGH LOAD ALARM. 4. THE OTS (OVERCURRENT TRIP SWITCHES) WILL OPERATE DIRECTLY FROM THE DIGITRIP DRIVING THE TA (TRIP TUATOR) TO TRIP THE CIRCUIT BREAKER. THE OTS REQUIRES A MANUAL LOCAL RESET VIA RED BUTTON DEPRESSION. + Figure 2- Connection Diagram for Narrow and Standard Frame with Digitrip 220/520/520M/520MC TD030003E
