14.5 Auxiliary power socket
Connecting electrical equipment to the Auxiliary Power
outlet will result in the establishment of a “ME System” and
may result in a reduced level of safety. The corresponding
standard requirements for “ME Systems” must be observed.
Output voltage 100–230 V AC
Fuse T1 AH, 250 V
Max. permitted power
consumption of the
secondary device: 100 VA
Max. permitted ground leakage current for the
LeicaM844 F40 including secondary device,
LeicaM844 CT40 including secondary device,
LeicaM844 F20 including secondary device:
IEC/EN 60601-1: 5 mA
UL 60601-1: 300 µA
If the ground leakage current exceeds the permitted limit value, the
following measures are required:
•
Secondary device does not conform to IEC/EN 60601-1 (EU) / UL
60601-1 (USA):
Connection via isolating transformer.
•
Secondary device conforms to IEC/EN 60601-1 (EU) / UL 60601-1
(USA):
Establish connection via potential equalization or connection
via isolating transformer.
