tory equipment, and IEC 60601-1 for medical equipment.) Furthermore all configura-
tions shall comply with the system standard IEC 60601-1-1. Anyone who connects
additional equipment to the signal input part or signal output part is configuring a
medical system, and is therefore, responsible that the system complies with the
requirements of the system standard IEC 60601-1-1. The unit is for exclusive inter-
connection with IEC 60601-1 certified equipment in the patient environment and IEC
60XXX certified equipment outside of the patient environment. If in doubt, consult the
technical services department or your local representative.
Grounding reliability can only be achieved when the equipment is connected to an
equivalent receptacle marked “Hospital Only” or “Hospital Grade”.
Use a power cord that matches the voltage of the power outlet, which has been
approved and complies with the safety standard of your particular country.
Caution! Use suitable mounting apparatus to avoid risk of injury.
