4.5.1 About electrical compliance
RRLQ_V3
Equipment complying with:
▪ EN/IEC 61000‑3‑11
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.
▪ 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 ≤75A.
▪ 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
.
▪ EN/IEC 61000‑3‑12 provided that the short-circuit power S
sc
is
greater than or equal to the minimum S
sc
value at the interface
point between the user's supply 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 >16A and ≤75A 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
sc
greater than or equal to the
minimum S
sc
value.
