IEC 61000-4-2 ± 6kV contact
± 8kV air ± 6kV contact
± 8kV air Floors should be wood, concrete or
ceramic tile. If floors are covered with
synthetic material the relative humidity
should be at least 30%.
Connectors marked with ESD symbol
excluded.

Mains power quality should be that of a
typical commercial or hospital
environment. If the user of the Giraffe/
Panda Warmer requ continued
operation during power mains
interruptions, it is recommended that the
Giraffe/Panda Warmer be powered from
an uninterruptible power supply or a
battery.
