This morning, the second revision and subsequent UPS update took place along with the replacement of the entire battery pack on the protected circuit designated DC6 A.
The entire operation lasted 170 minutes with a single goal, to fix network A so that it would have sufficient transition capacity and be able to backup the entire circuit during power outages without emergency failure. Throughout the entire time, part of the network was protected through backup circuit C. Complete battery replacement was successful including final monitoring and evaluation by the supplier. 
The battery replacement on circuit A was planned by the company for May 2017, however due to inconsistent UPS behavior in recent days and after UPS supplier supervision, it was decided to update and replace in the shortest possible timeframe.
Given the massive investment in electrical installation in June 2016, strengthening DC6 circuit B with new UPS and the current operation together with battery replacement on network A, trouble-free long-term operation of DC6.cz and Greenhousing services is expected. Used batteries were taken away for ecological disposal. Zdeněk Maršál Greendata s.r.o.
