Fig. 4-1: Wiring for DC Input
Instructions for DC use:
a)
Use a battery or a similar DC source. A supply from the
intermediate DC-bus of a frequency converter is not
recommended and can cause a malfunction or damage the
unit.
b)
Cpole to L and –pole to N.
c)
Connect the PE terminal to an earth wire or to the machine
ground.
Input Inrush Current
An active inrush limitation circuit (NTCs, which are bypassed by a relay contact) limits the input inrush current after turn-on
of the input voltage.
The charging current into EMI suppression capacitors is disregarded in the first microseconds after switch-on.
