We had our University electricians in today connecting our 2010 vintage AvIII
Nanobay instrument to the house backup generator in case of longer power outages.
They also assembled the new Liebert UPS unit that we purchased for the system
recently.
When they reached the point of connecting the new UPS to the Avance console,
they found the UPS was set up to deliver 30 amp service while the console
plug was 20 amp.
The way they resolved this (I had to leave for a medical appointment and was
unable to weigh in on this choice) was to replace the console's 20 amp plug
with a 30 amp plug to match the UPS outlet.
I have not powered up the instrument out of fear that 30 amps may fry some
components of our system, which is past its lifetime for maintenance support.
We cannot afford to replace the console if components fail.
I am sending this inquiry on a parallel path with an inquiry to Bruker. I have
no electrical competencies. Can anyone tell me whether a system designed to
run on 20 amps can be safely run on 30 amp service, or do I need to have
electricians back in to cut the plug (and UPS) down to 20 amp service?
Thanks for any reflections folks care to share.
