Electromagnetic
environment - guidance
Floors should be wood, concrete or
ceramic tile. If floors are covered with
synthetic material, the relative humidity
should be at least 30%
Mains power quality should be that of a
typical commercial or hospital environ-
ment.
Mains power quality should be that of a
typical commercial or hospital environ-
ment.
Mains power quality should be that of a
typical commercial or hospital environ-
ment. If the user of the CONCHATHERM
NEPTUNE Humidifier requires continued
operation during power mains interrup-
tions, it is recommended that the
CONCHATHERM NEPTUNE Humidifier be
powered from an uninterruptible power
supply or a battery.
Power frequency magnetic fields should
be at levels characteristic of a typical
location in a typical commercial or hos-
pital environment.
NOTE
U
T
is the a.c. mains voltage prior to application of the test level.
