Rack-Mounting Guidelines

Lightning and AC Power Fault Interference
As this product is safety certified for indoor connection only, if signal wires exceed recommended cabling
distances, you should consider the effect that a lightning strike in your vicinity might have on the controller.
The electromagnetic pulse (EMP) generated by lightning or other high-energy phenomena can couple enough
energy into unshielded conductors to damage or destroy electronic equipment. If you have previously
experienced such problems, you should consult with RFI/EMI experts to ensure that you have adequate
electrical surge suppression and shielding of signal cables in your controller operating environment.
