21.1 How to Connect Auxiliary Devices Safely
Basic Concept:
The Voluson® 730Pro is equipped with an isolation transformer to provide the required separation
from mains for both the system and auxiliary devices. These mains outlets are accessible at the rear of
the unit after removing the rear panel.
Video Copy Processors (VCP) and Video tape recorders (VTR) are to be connected here as described
in the chapter Connections.
The Voluson® 730Pro provides several inputs and outputs (I/O) such as Audio, Video, Ethernet, USB,
DICOM and Printer signals. Special care must be taken when connecting these terms to other devices.
The IEC 60601-1-1 standard provides a guideline for safely interconnecting medical devices in
systems.
“Equipment connected to the analog or digital interface must comply with the respective IEC/UL
standards (e.g. IEC 950/UL 1950 for data processing equipment and IEC 60601-1/ UL 2601-1 for
medical equipment). Furthermore, all configurations shall comply with the system standard
IEC 60601-1-1. Everybody who connects additional equipment to the signal input portion or signal
output portion configures a medical system, and is therefore responsible that the system complies with
the requirements of the system standard IEC 60601-1-1. If in doubt, consult the technical service
department or your local representative.”
1.) The medical device may be connected to a single IEC XXX device ( protection class I) placed in a
room which is not medically used.
2.) If the device is to be connected in a medically-used room the following rule applies:
a.) IEC 60601 compliant devices may be connected as such.
b.) IEC XXX compliant devices (protection class I) may be connected with an additional safety
measure.
For all situations 1 and 2, the additional device shall be installed outside the patient environment.
Additional protective earth connection between the 2 devices,
or a safety isolation mains transformer for the other device.
Special care has to be taken if the device is connected to computer network (e.g., Ethernet), because
other devices could be connected without any control of safety.
The user must use an isolated signal link according IEC XXX (4kV isolation barrier) to avoid the risk
of electrical shock and data corruption. review: Connector Panel (rear side)
(chapter 21.2.5)
Additionally the IEC60601-1-1 requires control measurement of leakage currents.
The system integrator (any person connecting the medical device to other devices) is responsible that
the connections are safe.
