Note: According 0701-0702, alternative leakage current easurem ents are only permitted,
if the previous insulating resistance easurem ent has been passed! alternative easurem ent
might lead results which exceed the adm issible limiting values (e. caused bypass capacitors
in the test sam ple). this case, use the direct differential current easurem ent method. Connect the mains plug the appli
