Accessory equipment connected to these interfaces must be certified according to the respective
IEC/EN standards (e.g. IEC/EN 60950 for data processing equipment and IEC/EN 60601-1 for
medical equipment). Furthermore all configurations shall comply with the valid version of the
system standard IEC/EN 60601-1-1. Everybody who connects additional equipment to the signal
input connector or signal output connector configures a medical system, and is therefore
responsible that the system complies with the requirements of the valid version of the system
standard IEC/EN 60601-1-1. If in doubt, contact our technical service department or your local
distributor.
