Electromagnetic Compatibility
Device suitable for:
Industrial applications Yes
Domestic applications No
Immunity against electrostatic discharge
(ESD):
According to IEC 61000-4-2, zone B, crite-
rion A
Electrostatic voltage in case of air dis-
charge
8 kV
Electrostatic voltage in case of contact dis-
charge

ESD with communication connectors In order to prevent operating malfunctions,
it is recommended, that the operating per-
sonnel discharge themselves prior to
touching communication connectors or
perform other suitable measures to reduce
effects of electrostatic discharges.
Immunity against the influence of radiated
(CW radiated):
