Guidance and manufacturer’s declaration – electromagnetic immunity (table 2 according IEC 60601-1-2)
The telescopic pillars CPMA and CPMB are intended for use in the electromagnetic environment specified below.
The customer or user of the telescopic pillars should ensure that they are used in such an environment.

Mains power quality should be that of a typical commercial or
hospital environment. If the user of telescopic pillars CPMA and
CPMB requires continued operation during mains power
interruptions, it is recommended that the telescopic pillars CPMA
and CPMB are powered from an uninterruptible power supply or a
battery.

3 A/m 3 A/m If distortion occurs, it may be necessary to position the telescopic
pillars CPMA and CPMB 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.
