Good afternoon!

Does anyone use UPS on Stack Systems?

I am in the process of sorting out a setup on 2 Olympus stacks.

H'mmm ... a special case - a "one off" - then (and hopefully with just a temporary solution required).

If I were you I would pass this one "upstairs" for a decision by the Big Boys. You know, those folk who take the Big Bucks.

Risk Assessment - Cost-Benefit Analysis - expenditure.

Meanwhile, if you have contractors on site, why not seek a solution (quote) from them?

@Malcolm: (voltage) stabilizer? Are the supplies in Roma that poor, then? Otherwise, what purpose do they serve? I saw many (of the older "servo" type) in Foreign Climes, and always considered them a waste of money. When the power failed (as it did at least daily in some places) - then "off" meant "off"!

Even the Nightingale hospitals fully meet the requirements set out in BS 7671 section 710 (IEC 60364-7-710). You can't mitigate away the requirements for the electrical installations in medical locations by "sticking a UPS" onto a medical device!

Also remember you are creating (or modifying) a ME System. This is not just an electrical safety issue (leakage current, EMC, etc.) but a design change. Will the UPS handle the inrush current, can you start up the UPS without a mains input, what happens if the UPS overloads, etc.

My advice, as Geoff said, step away and pass this upwards!
