DC

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) Connect +pole to L and –pole to N.

c) Connect the PE terminal to an earth wire or to the

machine ground.

An active inrush limitation circuit 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.
