5.3.1 Use of Additional Electromedical Equipment
When additional mains-operated electrical (electromedical) equipment such as infusion pumps,
data processing devices, ECG/EEG devices, etc., is used in combination with this electrically ad-
justable bed, the entire arrangement constitutes an ‘electromedical system’.
When using electromedical equipment, precautions must be taken to comply with electromagnetic
compatibility (EMC) requirements and allowable leakage current limits. The installation and com-
missioning of electromedical devices must be carried out in accordance with the EMC recommen-
dations described in their accompanying documentation. If necessary, the bed, and also the addi-
tional equipment associated with the bed, should be connected to the hospital’s potential equalisa-
tion (PE) system (using the connection pin at the head end of the bed).
When the bed is connected to the mains electricity supply, it must always be connected to the
hospital’s potential equalisation system when intravascular and intracardial applications are in-
volved. The potential equalisation of this electric bed applies to the mattress base frame. Addition-
al assembly groups and accessories (such as headboards and footboards, safety sides, patient
lifting poles, infusion stands) are excluded from these requirements.
In addition, observe the information given in:
x Chapter Safety Information Concerning the Place of Use » 36 and Chapter Electromagnetic In-
terference » 17.
x All the information given in the instruction manuals of the additional devices as well as the re-
quirements stipulated in the relevant standard EN 60601-1, Chapter 16 (formerly EN 60601-1-
1).
