I'm about to return to the US after a 3 year job contract here in OZ. I assume that if I set my Saeco Royal Professional up with it's own 240V receptacle, It will operate just as it does in Australia? In the US system, each of two hot wires carries 120V to ground and 240V between the two. Does anyone have a schematic of the Saeco unit?

Re: Compatability with US 240v 60HZ 1phase wiring?
It should work OK The US system is 240V single phase (split) into two 120v branches. Aussi system is hot on both sides, with a center ground (a virtual ground system) Connect the 2 main wires (usually brown and blue) to the 240 (black and red), and connect the grounds (Green/yellow to green), and leave the neutral wire off.

for a start - if you want correct answer, then provide model, original voltage. if i am judging it from the picture this is skill floorboard saw made for us market (110/115v 60hz), you cannot rewire the motor - full stop! purchase step down transformer 240v/110v 6amps to 10amps, if in australia - this transformer will set you back about $60.00 if in euro, this transformer (depending on country) will cost you anything between 40euro and 60euro. transformer will have cable on one side for connection to the main and socket to connect to the saw cable.
you can modernise this arrangement by permanently mounting the transformer on the saw (there is enough room on the end of the runner to mount it there), cut the cable to sufficient length and connect it to the transformer on 110v side, leave as is on 240v side.
YOU CANNOT REWIRE FROM 240V TO 110V, NOR FROM 110V TO 240V to do so you will need to rewire rotor as well as stator, and that unfortunately is not really easy job... i know i was doing that about 50 years ago...

you must understand this : your electric oven must be indicate if it is a single phase( use 3 wires for 230 2 hot wires + 1 Neutral see the diagram like dryer? you must sure about this. Normally any appliance for home are single phase NOT 3 phase.
2) If you electric oven, say 3 PHASES( use 4 WIRES, 3 hot wires+1 Neutral wires) this for industrial application +comercial NOT for home
However if you system is 3 phase you must need to install 3phase transformer.
Extensive analysis revealed this unit to be for 120V 60Hz regions. If you use it in a region where the mains supply is 220/240V 50Hz then it won't work. In addition, the PSU will overheat, with possible damage to other modules.
One possible solution is a 120V 60Hz inverter, else Samsung may be able to provide the correct PSU for 220/240V.
Setting your dose at max and grinder at finest is not good. This means that you are asking the machine to grind coffee really fine, and then dose maximun amount which can lead to the grinder getting clogged. If you are looking for stronger coffee, it is best to have several shots that one that has too much coffe and too fine. For stronger espresso, use less water instead of more coffee. Two shots of 2 oz. espresso (made with 7 grams of coffee) are more flavorful & sweeter than one shot of 4-oz. espresso made with 14 grams of coffee which could clog your grinder and door/channel. At this point, you need to clean the grinder ( inlcuding the door/channel).
I suggest you have an Authorized SAECO Service Center check your machine. Contact Saeco USA Inc. to located a Service Center near you at 800-933-7876 (toll-free), ask for customer support, or contact SAECO via e-mail at : firstname.lastname@example.org
Your idea is basically sound and should work as long as the UPS originally is designed to produce 240V 60Hz and has its own built in timebase. The reason is that the input as long as the voltage matches makes no difference (50 or 60 Hz). By design, the UPS converts the input voltage to DC to charge the internal battery. The battery then powers an electronic circuitry that produces the 240V 60Hz. The input is then isolated from the output in terms of frequency. This is a common design, however, there are some (not many) that uses for its local oscillation sampling from the source and therefore will replicate the input frequency to its output, but very rare; it's better that you know they exist.
Hope this be of some help/idea. Post back how things turn up or should you need further information.
Good luck and kind regards.
The only problem with 50 and 60 Hz is heat buildup which is tolerable and still within safe parameters. The only time the 50/60 HZ makes a big difference is when motors are used, timers such as in the early designs of microwave ovens, washing machines, etc., pumps and other highly inductive consumers. Most electronic devices converts the AC input to DC and therefore the frequency has negligible effect. Of course others may see it differently.
