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
.
