Establishing the power supply, 3~/400V
Caution.
Risk of material damage due to high con-
nected voltage.
At mains voltages greater than 440 V, elec-
tronic components may be damaged.
▶
Ensure that the nominal voltage of the 3-
phase mains is 400 V (+10%/-15%).
Caution.
Risk of material damage due to large
voltage difference.
If the voltage difference between the indi-
vidual power supply phases is too large, this
can lead to the product malfunctioning.
▶
Ensure that the voltage difference
between the individual phases is below
2%.
▶
Determine the type of connection:
