Application Notes

EAP-030041

A control room instrument was damaged during a recent lightning strike. What can be done to prevent this damage in the future?

If possible, determine exactly where the lightning entered the instrument. In all probability, it entered through the input signal line or power supply line. We would recommend that you use a protector on both the signal and power supply lines. Contact your local sales office for specific models for your application.
