 WARNING

VERIFY CIRCUIT BREAKER IS OPEN, CLOSING SPRINGS ARE 

DISCHARGED AND CONTROL POWER IS DISCONNECTED. 

REFERENCE: THE SPRING RELEASE COIL IS THE COIL ON THE 

LEFT SIDE, LOOKING INTO THE CIRCUIT BREAKER, WITH 

THE GREEN “PUSH TO CLOSE” LABEL. THE SHUNT TRIP 

COIL IS THE COIL ON THE RIGHT SIDE, LOOKING INTO THE 

CIRCUIT BREAKER, WITH THE RED “PUSH TO OPEN” LABEL.

Installation of Second Shunt Trip

Make sure all warnings are adhered to and circuit 

breaker is closed and discharged.
Make sure area is prepared for installation of 2nd Shunt 

Trip, move wires down out of the way.

otee:

N

Routing of wires, make sure 2nd Shunt trip wires route 

the same way.

Place aluminum shim on back of 2nd shunt trip as 

shown.
Hold shim in place while you begin installation.
Make sure wires are routed through the same opening 

as the existing.
Install 2nd Shunt Trip next to existing Push to Open 

Assembly as shown, hand tighten center bolt. Make 

sure aluminum shim does not fall out. Make sure steel 

brackets that stick out to the left are properly oriented as 

shown.
Install .312-18 X .625 socket head capscrew in lower 

right hole in 2nd Shunt Trip Bracket as shown. This uses 

a .250-20 Hex Allen Wrench.
Tighten socket head capscrew as shown, making sure 

aluminum shim is still in place. Tighten center .312-18 

hex bolt using a ½” or 13mm socket or wrench.
Attach wires to the 5th and 6th location on the terminal 

block as shown. Use wire ties as needed to bundle 

wires together so they do not interfere with other 

components.
