2.2. Operating Safety
In the safety operating scope, the ND1 Power Analyzer meets requirements
related to safety of electrical measuring instruments for automation, acc. to EN
61010-1 standard and requirements concerning the immunity against noises
occurring in industrial environments acc. to EN 61000-6-2 and EN 61000-6-4
standards.
The improper connection of the supply, communication interfaces and measuring
signals, and the use of equipment inconsistent with the description included in the
prese

2.2.1. Remarks Concerning the Analyzer Installation
Various sources of noise occurring in practice interact with the ND1 Power
Analyzer in a continuous or pulse way from the supply network side (as the result
of the action of other devices) and also overlap on the measured signal or auxiliary
circuits of the analyzer. Noises occur also when switching capacitive-inductive
loads by own analyzer alarm relays.
