When establishing an electrical connection with other devices and when operating the device on a
portable multiple socket outlet, ensure compliance with IEC 60601-1 in the currently valid version.
To maintain conformity with the standard, so-called "decoupled interfaces" are provided for this
case for the RJ-45 port (LAN1) and, depending on the configuration, one or both RS232 ports. Data
can be transmitted via these galvanic isolators without a direct electrical connection. From an elec-
trical point of view, the connection of medical devices is permitted at these decoupled interfaces.
At the same time, a functional unit is created when exchanging data with other devices. This
applies in particular if this functional unit has a medical purpose (e.g. control of infusion pumps by
the device, connection of application parts). The validity of any assured standard conformities and
properties of the device would not extend to the new functional unit. Instead, the person placing
the new functional unit on the market is responsible for its conformity to applicable regulations
and standards.
Should the device be brought into contact with other devices, unforeseen interactions or even
malfunctions may occur on one or both devices.
