CPMT
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.

synthetic material, the relative humidity
should be at least 30%.

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

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.
