C2 Features of Power Supply
The AC power supply at the machine must meet
the following conditions:
•
Max. Fluctuation of voltage: ± 10%
•
Max. Fluctuation of frequency: ± 1%, with
short-time endurance of ± 2%.
The harmonic distortion, unbalanced 3 - phase
supply voltage, voltage impulse, power failure,
sudden drop and other electrical characteristics
must comply with the standard EN60204-1
(IEC60204-1), sub clause 4.3.2.
Important Information!
The machine power supply must be
