This equipment (LRYEN10A7Y1 and LRNUN5A7Y1) complies with:
▪ EN/IEC 61000‑3‑11 provided that the system impedance Z
to Z at the interface point between the user's supply and the public system.
max
- EN/IEC 61000‑3‑11 = European/International Technical Standard setting the
limits for voltage changes, voltage fluctuations and flicker in public low-voltage
supply systems for equipment with rated current ≤75 A.
- It is the responsibility of the installer or user of the equipment to ensure, by
consultation with the distribution network operator if necessary, that the
equipment is connected only to a supply with a system impedance Z
or equal to Z .
max
▪ EN/IEC 61000‑3‑12 provided that the short-circuit power S
equal to the minimum S
and the public system.
- EN/IEC 61000‑3‑12 = European/International Technical Standard setting the
limits for harmonic currents produced by equipment connected to public low-
voltage systems with input current >16 A and ≤75 A per phase.
- It is the responsibility of the installer or user of the equipment to ensure, by
consultation with the distribution network operator if necessary, that the
equipment is connected only to a supply with a short-circuit power S
than or equal to the minimum S
