Electrostatic Discharge (ESD) IEC 61000-4-2
±6 kV contact ±8 kV air
±6 kV contact ±8 kV air
Floors should be wood, concrete, or ceramic tile. If floors are covered with synthetic material, the relative humidity should be at least 30%.
Electrical fast transient/burst IEC 61000-4-4
±2 kV for power supply lines ±1 kV for input/output lines
±2 kV for power supply lines ±1 kV for input/output lines
Mains power quality should be that of a typical public low-voltage power supply network that supplies hospitals or buildings used for commercial or domestic purposes.
