Pulse-shaped disturbance
The following table shows the electromagnetic compatibility of modules with regard to pulse-
shaped interference. The precondition for electromagnetic compatibility is that the HMI
device meets the specifications and guidelines for electrical installation.

Sinusoidal interference
The following table shows the EMC behavior of the modules with respect to sinusoidal
interference. This requires the HMI device to meet the specifications and directives for
electrical installation.
