6. INPUT INRUSH CURRENT
An active inrush limitation circuitry 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 milliseconds after switch-on.

Instructions for DC use:
a) Use a battery or similar DC source.
b) Connect +pole to L and –pole to N.
c) Connect the PE terminal to a earth wire or
to the machine ground.
In case the –pole of the battery is not connected
to earth, use an appropriate fuse to protect the N
terminal.
