This equipment 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

INFORMATION
Multi units are standard combinations.
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 table below.
