Table 5: Immunity
Data
Value
Immunity against electrostatic discharge
(ESD)
According to EN 61000-4-2, zone B, criterion
B
-> Interference voltage with air discharge
8 kV
-> Interference voltage with contact discharge 4 kV
ESD with communication connectors
Ensure that any electrostatic charge is dis-
charged prior to contact with the communica-
tion connectors (e.g. by touching an earthed
metal object). Otherwise malfunctions may
occur.
ESD module carrier connectors
Do not touch the plug connecting the module
carrier on the bottom side of the device.
ESD external coupler interface
Do not touch the plug to the flat ribbon cable.
Immunity against the influence of radiated
interference (CW radiated)
According to EN 61000-4-3, zone B, criterion
A
-> Test field strength
10 V/m (except ITU transmission bands 87…
108 MHz, 174…230 MHz and 470…790 MHz
-> 3 V/m)
-> Maximum temporary deviation during irradi-
ation
Analog current output signals max. 1.5 %.

AD
Immunity against transient interference vol-
tages (burst)
According to EN 61000-4-4, zone B, criterion
