Electromagnetic Immunity
The Medela Vario 18 AC/DC c/i are intended for use in the electromagnetic environment spe-
cified below. The customer or the user of the Medela Vario 18 AC/DC c/i should assure that
they are used in such environment.

± 6 kV contact Floors should be wood, concrete or
± 8 kV air ceramic tile. If floors are covered with
synthetic material, the relative humidi-
ty should be at least 30 %.

for power a typical commercial or hospital envi-
supply lines ronment.

Vario 18 AC/DC c/i requires conti-
40 % UT nued operation during power mains
(60 % dip in UT) interruptions, it is recommended that
for 5 cycles the Medela Vario 18 AC/DC c/i be po-
wered from an uninterruptible power
