Safeguard patients and equipment

In group 2 medical locations, the priorities are safety and operational continuity. To meet these requirements, and in accordance with the installation standard IEC 60364-7-710, the IMD must be able to always notify the operator in the event of a first insulation fault. If the IMD malfunctions and the operator is not alerted to the first fault, then a second fault can cause a short circuit.

As required by the installation standard IEC 60364-6, a periodic installation inspection, which includes the IMD, must be conducted by an accredited body. Each country sets the inspection interval time.


Where can insulation be monitored in a group 2 medical facility ?

The TN earthing system is generally used within the hospital except for group 2 locations where medical equipment and systems used for surgical applications located in the patient environment are supplied with a medical IT system.

During the verification checks, it is recommended to check the compliance of the IMD wiring and fault locators, as well as their correct positioning in terms of monitored loads. Also the effectiveness of the insulation fault locators and that the audible and visual alarms are functioning properly, by simulating insulation faults on the installation have to be validated.
