Direct tapping of LV
HRC fuses
Using the measuring cable MK 55 (available as a special accessory - see section 3.3)
the test voltage can be directly tapped from LV HRC fuses of size 00 – 3 (6 … 630 A).
Observe the following safety instructions when using the measuring
cable MK 55:
• The measuring cable MK 55 may only be used by qualified
electricians or persons who have been instructed in electrical
principles.
• Only safety handles conforming to DIN VDE 0636-201
(EN 60269-2) or DIN VDE 0680-4 (for work performed under live
voltage) may be used for operation.
• When performing assembly work under live voltage, the work-
specific instructions and documentation of the network operator,
as well as national safety regulations (such as the German TRBS
2131) are to be observed.
• It is not intended that the fuse in the plug-in adapter of the
measuring cable be replaced by the user.
