Electric connection
Before connecting the power cable, be sure to have a proper power outlet.
Make sure that the electrical outlet of the mains supply is the Schuko type; and is dimensioned on the basis of the characteristics of
the equipment. Make sure there is an Earth connection.
Apply a "D" type disconnect device upstream of the equipment connection cable with the mains.
The disconnect device must be paired with an overcurrent protection device equipped with a circuit breaker. The characteristics of
such devices must be such as to meet the applicable regulations in the country of installation, and are dimensioned according to the
equipment specifications.
Power supply tolerances
•
Working voltage
±
10% of rated voltage.
•
Frequency:
±
1% of rated current in continuous mode
±
2% of rated current for a short period
•
Harmonic distortion for the sum of the second to fifth harmonics not over 10% of the total voltage rms among conductors. A further
distortion is allowed for the sum of the harmonics from the sixth to thirtieth of 2% on the total voltage rms among conductors.
•
Voltage pulses should not be longer than 1.5ms with a rise/decay time between 500ms and 500μs and a peak value not exceeding
200% of the effective value of the rated power supply voltage.
•
The power supply must not be interrupted nor drop to zero for more than 3ms at any instant of the power wave. There must be no
more than 1s between two subsequent breaks
•
The voltage dips must not exceed 20% of the power supply peak voltage for more than one cycle. There must be no more than 1s
between two dips.
