Point for attention regarding quality of the public electric power supply
This equipment complies with respectively:
- EN/IEC 61000-3-12 provided that the short-circuit power Ssc is greater than or equal to the mini-
mum 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 distri-
bution network operator if necessary, that the equipment is connected only to a supply with re-
spectively: Ssc greater than or equal to the minimum Ssc value.
- 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.

Precautions when laying power wiring
Use round pressure terminals for connections to the power terminal block.
Round pressure terminal
Power cable
When none are available, follow the instructions below.
- Do not connect wiring of different thicknesses to the power terminal block. (Slack in the power
wiring may cause abnormal heat.)
- When connecting wiring which is the same thickness, do as shown in the figure below.
WARNING
Make sure that the screws of the terminal are free from looseness.
