Figure 3-27: Connection Diagram for Double-wide Frame with Digitrip 520/520M/520MC with ABCABC Configuration
NOTES:
1. 4 WIRE CRIMP CONNECTION
2. 3 WIRE CRIMP IF HIGH INST TRIP MODULE IS SUPPLIED.
3. WIRE CONNECTION USED WITH DIGITRIP 520M/520MC GROUND ALARM POWER SUPPLY
MODULE WILL "HANG UNCONNECTED" IF DIGITRIP 220 OR 520 IS SUPPLIED.
4. ALL AUX SWITCHES 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 ACCESSORY CONSISTS OF A "SR" COIL AND A P.C. BOARD. THE
PRINTED CIRCUIT BOARD 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) 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.
