Preface Translated Safety Warnings Distance Limitations for Signaling and Unshielded Conductors Give special consideration to the effect of a lightning strike in the site vicinity if wires exceed recommended distances, or if wires pass between buildings. The electromagnetic pulse (EMP) caused by lightning or other high-energy phenomena can easily couple enough energy into unshielded conductors to destroy electronic devices. Provide a properly grounded and shielded environment.
