Max. permitted power
consumption of the
secondary device:
Max. permitted ground
leakage current of the
secondary device:
Required conformity of the
secondary device:
If the device does not conform, it must be connected via an
isolating transformer.
If the ground leakage current exceeds the permitted limit value,
the following measures are required:
• Device does not conform to EN 60601-1 (Europe) / UL 60601-1
(USA): Connection via isolating transformer.
• Device conforms to EN 60601-1 (Europe) / UL 60601-1 (USA):
Connection via potential equalization or isolating transformer.
