environment - guidance
Floors should be wood, concrete or
ceramic tile. If floors are covered with
synthetic material, the relative humidi-
ty should be at least 30 %.
Mains power quality should be that of
a typical commercial or hospital envi-
ronment.
Mains power quality should be that of
a typical commercial or hospital envi-
ronment.
Mains power quality should be that of
a typical commercial or hospital en-
vironment. If the user of Invia Liberty
requires continued operation during
power mains interruptions, it is re-
commended that Invia Liberty be po-
wered from an uninterruptible power
supply or a battery.
Power frequency magnetic fields
should be at levels of a typical com-
mercial or hospital environment.
