If you are trying to reset an overload relay from outside the control panel, or if your current overload relay is stuck in the tripped state, you can resolve this by adding an external reset switch.
*Note: This is for EMPR (Electronic Motor Protection Relays) systems*

Why Add an External Reset Switch?

In many installations, the overload relay’s reset button is located inside the control panel. This can be inconvenient or even hazardous if frequent panel access is required.
To simplify operations and improve safety, you can wire an external reset switch, allowing you to reset the overload without opening the control panel door.

How to Wire an External Reset Switch

1. The red box in the diagram highlights the external "Off (Reset)" switch
   
2. This is a momentary normally-open (NO) switch that, when pressed, sends a reset signal to the EMPR (overload relay), clearing the trip state.
3. The wiring shows the reset switch connected in series with the control circuit, allowing an operator to reset the system without opening the panel.
   

Summary

Adding an external reset switch is a simple and effective way to:

• Improve convenience and accessibility

• Reduce downtime

• Enhance operator safety by avoiding unnecessary panel access
