1) Calculation according to IEC 60939-1, annex A, at rated voltage and 50 Hz.In practice are up to double values to be expected due to
the insulation resistance values of the used ceramic capacitors. For the medical version results computationally the value 0. In practice
are values 1 ... 2
μA
to be expected due to the insulation resistance values of the used materials.

Safety Notices
fuses
All safety rules for working with electricity must be observed.
Fuses may only be changed when they are not under voltage and by a qualified electrician or
technician.
The fuse holder must be closed before connecting the device to the mains.
The person responsible for the system must select a suitable fuse (not included with the
original product shipment), taking into account the specifications of both the filter and the
systems.
