According to EN 61000-4-2, zone B, criterion
B
8 kV
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.
Do not touch the plug connecting the module
carrier on the bottom side of the device.
Do not touch the plug to the flat ribbon cable.
