Ensure the safety of medical locations

The safety of medical locations, as defined by the installation standard IEC 60364-7-710, and its European (HD 60364-7-710) and French (NF C 15-211) transpositions require the following actions and requirements:

  • Prevent protection tripping on group 2 locations using in an IT earthing system by incorporating an insulation transformer in accordance with IEC 61558-2-15.
  • Be alerted to first faults with the help of an insulation monitoring device for a group 2 installation meeting the specific characteristics of the medical environment according to the standard IEC 61557-8. Associated fault locators must comply with IEC 61557-9.
  • Switch in case of loss of power using automatic transfer switching equipment (ATSE according to IEC 60947-6-1, or STS according to IEC 62310). The break times defined by the installation standard must be applied to groups 0, 1 or 2.

All this equipment must be integrated into an IEC 61439-certified switchboard. An initial and periodic inspection is required.

Select the right safety level

The standard IEC 60364-7-710 categorises medical location into three groups, according to the risk of electric shock.

Group 0

Medical location where no applied parts are intended to be used.

Group 1

Medical location where applied parts are intended to be used as follows externally or invasively to any part of the body, except where Group 2 applies.

Group 2

Medical location where applied parts are intended to be used in applications such as intracardiac procedures, operating theatres and vital treatment where discontinuity of the supply can cause danger to life.

What is an applied part?

An applied part is a part of the medical electrical equipment which in normal use necessarily comes into physical contact with the patient for the equipment to perform its function, or can be brought into contact with the patient, or needs to be touched by the patient.
