Electromagnetic
discharge (ESD)
IEC 61000-4-2
±8 kV contact
±15 kV air ±8 kV contact
±15 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

IEC 61000-4-4
±2 kV for power
supply lines; ±1 kV for
input/output lines
+2 kV for power

Main power quality should be that of a
typical commercial or hospital environment.
The warmer does not have any input/output
lines.

Mains power quality should be that of a
typical commercial or hospital environment.
If the user of the warmer requires continued
operation during power mains interruptions,
it is recommended that the warmer be
powered from an uninterrupted power
supply or a battery.

30 A/m 30 A/m Power frequency magnetic fields should be
at levels characteristic of a typical location in
a typical commercial or hospital
environment.
NOTE:
UT is the a.c. mains voltage prior to application of the test level.
