b) Connect +pole to L and –pole to N.
c) Connect the PE terminal to an earth wire or to the
machine ground.
5. Input Inrush Current
A NTC limits the input inrush current after turn-on of the input voltage. The inrush current is input voltage and
ambient temperature dependent.
The charging current into EMI suppression capacitors is disregarded in the first microseconds after switch-on.
