Pulse-shaped disturbance variables of the ET 200SP system
The table below shows the electromagnetic compatibility of the ET 200SP distributed I/O
system with regard to pulse-shaped disturbance variables.
Table 14- 1
Pulse-shaped disturbance variable Tested with
Electrostatic discharge in accord-
ance with IEC 61000-4-2
Burst pulses (fast transients) in
accordance with IEC 61000-4-4
High-energy single pulse (surge) in accordance with IEC 61000-4-5
External protective circuit required (see Function manual Designing interference-
free controllers (http://support.automation.siemens.com/WW/view/en/59193566))
