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 environment.
Mains power quality should be that of a typical commercial or
hospital environment.
Mains power quality should be that of a typical commercial or
hospital environment. If the user of the NU-IP40S requires
continued operation during power mains interruptions, it is
recommended that the NU-IP40S 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 hospital
environment.
