⚡ CPE – Central Potential Equalisation in Medical Locations
|
Mandatory per IEC 60364-7-710 / DIN VDE 0100-710: In Group 1 and Group 2 medical locations, a Central Protective Equipotential Bonding (CPE) system is mandatory. All conductive parts – enclosures, beds, infusion stands, pipework – are connected to a common bonding conductor (max. 0.1 Ωresistance) and protective earth. Purpose: fault currents cannot flow through the patient.
Group 1(X-ray, physiotherapy): leakage < 500 µA · Group 2(OR, ICU, cardiac cath lab): leakage < 10 µA · Inspection intervals: STKannually by qualified electrician, MTKevery 2 years by authorised inspector. |
⚡ Application Areas for Electrical Isolation Components
|
OR & Intensive Care
Group-2 locations: IT networks with monitoring, 2-MOPP power supplies, CPE with < 10 µA leakage. |
Imaging & Diagnostics
X-ray, CT, MRI: Group-1 requirements, leakage current limitation, insulation testing per IEC 60601. |
GP Practice & Outpatient
Minor procedures, ECG, ultrasound: isolation between mains and patient monitoring systems. |
|
Laboratory & IVD
Analysers, PCR systems: galvanic isolation prevents measurement interference from earth loops. |
OEM Medical Device Mfg.
Isolation components as device sub-assembly: certification evidence per EU MDR and IEC 60601-1. |
