8.2.3 Mounting notes
Protection against transients is mounted on DIN rails.
8.2.4 Regulations for installation
 Full scale protection against transients is based on a 3-stage protection concept:
Gas-filled charge eliminator – ZNR – suppressor diode
 The protective function is ensured only when the installation is correctly made!
 In accordance with regulations, the DIN rail must be connected to the rail for po-
tential equalization in the building
 For notes on installation of plant in compliance with EMC directives, refer to Data
Sheet N2034
 The polarity of the protective components must be observed! The device to be
protected must always be connected to output “OUT” of the protective device that
guards against transients
