FUSE

a) Use a battery or similar DC source.

For other sources contact PULS

b) Connect +pole to L1 and –pole to L2.

c) Use appropriate external fuses in the + and – lines which

are suitable for the DC-voltage.

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

ground.

e) DC-operation is not included in the UL approval.

Additional testing might be necessary.

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.
