About electrical compliance

This equipment complies with:
▪ EN/IEC 61000‑3‑11 provided that the system impedance Z
less than or equal to Z at the interface point between the user's
max
supply and the public system.
▪ EN/IEC 61000‑3‑11 =
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
▪ EN/IEC 61000‑3‑12 provided that the short-circuit power S
greater than or equal to the minimum S
point between the user's supply and the public system.
▪ EN/IEC 61000‑3‑12 =
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
minimum S value.

INFORMATION
Multi units are standard combinations.
5.4.2

Safety device requirements

The power supply must be protected with the required safety
devices, i.e. a main switch, a slow blow fuse on each phase and an
earth leakage protector in accordance with the applicable legislation.
For standard combinations
Selection and sizing of the wiring should be done in accordance with
the applicable legislation based on the information mentioned in the
is
sys table below.
INFORMATION
Multi units are standard combinations.
