a) Use a battery or similar DC source.

For other sources contact PULS

b) Connect +pole to L and –pole to N.

c) Connect the PE terminal to a earth wire or to the machine

ground.

An active inrush limitation circuit limits the input inrush current after turn-on of the input voltage and after short

input voltage interruptions.

The charging current into EMI suppression capacitors is disregarded in the first microseconds after switch-on.
