Guidance and manufacturer’s declaration – electromagnetic immunity (Table 2 - IEC 60601-1-2)
The telescopic pillar CPMT is intended for use in the electromagnetic environment specified below.
The customer or user of the telescopic pillar should ensure that it is used in such an environment.

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.

for 5 s
Mains power quality should be that of a
typical commercial or hospital
environment. If the user of the
telescopic pillar CPMT requires
continued operation during power
mains interruptions, it is recommended
that telescopic pillar CPMT is powered
from an uninterruptible power supply or
a battery.
Power frequency
(50/60 Hz)
magnetic field
IEC 61000-4-8
3 A/m
3 A/m
If distortion occurs, it may be necessary
to position the telescopic pillar CPMT
further from sources of power
frequency magnetic fields, or to install
magnetic shielding. The power
frequency magnetic field should be
measured in the intended installation
location to ensure that it is sufficiently
low.
Note:
U1 is the a.c. mains voltage prior to application of the test level.
