Correction

"Hello everyone! I want to address a mistake that occurred in the video at the 5:11. I apologize for any confusion caused. Upon reviewing the footage, I noticed that I incorrectly connected a wire from terminal 1 of the Phase Failure Relay to the common terminals 95 and 97 of the Overload Relay. The correct wiring should have involved taking the wire from terminal 3 of the Phase Failure Relay. I deeply regret this oversight.

To ensure the proper functioning of the system, please disregard the wiring shown in the video and follow the corrected connection mentioned earlier. I apologize for any inconvenience caused, and I appreciate your understanding and patience. If you have any further questions, please don't hesitate to reach out. Thank you for your support!"
