Working with products
from Megger
It is important to observe the general electrical regulations of the country in which the
device will be installed and operated, as well as the current national accident prevention
regulations and internal company rules (work, operating and safety regulations).
Use genuine accessories to ensure system safety and reliable operation. The use of other
parts is not permitted and invalidates the warranty.
Operating staff This system and its peripheral equipment may only be operated by trained or instructed
personnel. Anyone else must be kept away.
The system may only be installed by an authorised electrician. DIN VDE 0104 (EN 50191),
DIN VDE 0105 (EN 50110) and the German accident prevention regulations (UVV) define
an electrician as someone whose knowledge, experience and familiarity with the
applicable regulations enables him to recognise potential hazards.
