Figure 3-46 Magnum DSL Connection Diagram with Blown Fuse Trip Digitrip 1150
NOTES:
1. 3 WIRE CRIMP IF HIGH INST. TRIP MODULE IS SUPPLIED.
2. ALL CONTACTS SHOWN WITH BREAKER IN OPEN POSITION AND WITH TRIP UNIT IN “NON-TRIPPED” STATE (OTS
SWITCHES) AND SPRINGS NOT CHARGED.
3. THE SPRING RELEASE ACCESSORY CONSISTS OF A “SR” COIL AND A P.C. BOARD. THE PRINTED CIRCUIT BOARD PRO-
VIDES A .20 SECOND PULSE FOR THE CLOSING OPERATION. VOLTAGE MUST BE REMOVED AND THEN REAPPLIED FOR
SUBSEQUENT OPERATION.
AN OPTIONAL LATCH CHECK SWITCH (LCS) ACCESSORY 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 REAPPLIED TO THE SPRING
RELEASE FOR 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. A BREAKER EMPLOYIN THE GROUND FAULT FUNCTION, 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 OPENED CONTACT PROGRAMMED AS RELAY A. VIA DIGITRIP FRONT PANEL. (ALARM CONTACT).
7. NORMALLY CLOSED CONTACT PROGRAMMED AS RELAY B. VIA DIGITRIP FRONT PANEL. (BLOCK CLOSE CONTACT)
8. NORMALLY OPEN CONTACT PROGRAMMED AS RELAY C. VIA DIGITRIP FRONT PANEL. (LATCHING CONTACT)
9.(NA)
10. MOTOR OPERATOR SWITCH SHOWN WITH BREAKER CLOSING SPRING DISCHARGED.
11. 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 CONTACTS B-4, B-5, ARE NOT WIRED OUT.
12. FOUR POINT SOCKET USED HERE.
13. SECOND SHUNT TRIP MAY BE INSTALLED (USING A-7, A-8 CONTACTS) IN PLACE OF UVR. THIRD AUX SWITCH NOT
AVAILABLE WITH SECOND SHUNT TRIP.
14. ONLY ONE LATCH CHECK SWITCH MAY BE INSTALLED. USE OF CUSTOMER ACCESSIBLE LATCH CHECK SWITCH (B-29,
B-30) IN SERIES WITH SPRING RELEASE DEFEATS ANTI-PUMP FUNCTION AND IS NOT RECOMMENDED. SEE NOTE 3 FOR
SPRING RELEASE LATCH CHECK SWITCH.
15. THE OTS (OVERCURRENT TRIP SWITCHES) WILL OPERATE DIRECTLY FROM THE DIGITRIP DRIVING THE TA (TRIP ACTU-
ATOR) TO TRIP THE CIRCUIT BREAKER. THE OTS REQUIRES A MANUAL LOCAL RESET VIA RED BUTTON DEPRESSION.
16. FOR CIRCUIT BREAKERS BUILT AFTER JULY 2006 AND DITRIP 1150 UNITS OF FIRMWARE REV 20decimal OR GREATER,
THE MAINTENANCE MODE FEATURE (ARMS) IS SUPPLIED. THE REVERSE POWER DESELECTION IS FRONT PANEL PRO-
GRAMMABLE ONLY.
