Electrical equipment complying with 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).
(c)
This equipment complies with 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) provided that the system impedance Z
sys
is less than or equal to Z
max
at the
interface point between the user's supply and the public system. 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
sys
less than or equal to Z
max
.
