The device to be tested must be safely isolated from the AC mains supply. The
mains lead (L1, N, PE) must not be connected. Follow the safety rules.
The device to be tested must be safely isolated from the battery. The charging leads
must not be connected.
There must be no earthing connections present
No additional options should be connected to the battery charging system
The device must be isolated from the PC and other connections
The measurement is taken between the ground terminal of the device and every
conductive part that can be touched and that is connected to the ground conductor.
Should the original mains cable be with the battery charging system, the measure-
ment must be taken between the earthing of the mains cable and every conductive
part that can be touched and that is connected to the ground conductor. Move the
mains cable to detect any line breakage
The resistance must not exceed 0.3 W *)
