Why is my emergency stop push button working backwards with my shunt trip?

Issue:
Why is my emergency stop push button working backwards with my shunt trip?

Product Line:
22mm and 30mm push buttons - GIC Product

Environment:
US Product

Cause:
These applications are much less common than standard E-stop applications

Resolution:
Most shunt trip applications require a contact to close to initiate a trip.  Most standard emergency stop applications require a contact to open to iniate a stop.  Because the standard emergency stop application is far more common, emergency stops always come with a sindle NC contact or 1 NC and 1 NO contact.  If a shunt trip application is required wherein a contact must close to initiate, either wire to the NO contact if available or replce the NC contact with a NO.
