Uninterruptible power supply

We have decided to instead of changing some parts of the UPS that need replacing as they are aging but which are very expensive, to replace it by a new system. The new system is slightly smaller in capacity, but much more efficient, and capable of maintaining the whole system except the large cooling units (which also the old system did not cover). To simply things we will eliminate separate lines for normal, and uninterruptible power supply. With some modification to the cooling system (see below) this will allow the telescope to stay fully operable also when there is a general power-cut.
