Point for attention regarding quality of the public electric power supply
This equipment complies with respectively:
- EN/IEC 61000-3-12 (1) provided that the short-circuit power Ssc is greater than or equal to the
minimum Ssc value 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 respectively: Ssc greater than or equal to the minimum Ssc value.
• 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.
• European/International Technical Standard setting the limits for harmonic currents produced by
equipment connected to public low-voltage systems with input current ≤16 A of ≻75 A per
phase.
