Basic Faulting Finding :-
Check with a Multi-meter there is correct 230vAC on the input if no voltage check the fused spur
Check with a Multi-meter there is 54vDC voltage on the output if no voltage remove output wait 2 minutes for the thermal fuse to cool.
Retest after 2 minutes if still no voltage and 230vAC is present change the unit, there is no programming required for this unit.
