We have 2x APC symmetra LX 16kVA units running at the moment and have read (in Eaton's documentation) that their UPSs can have a common synchronised output (based on input phase or set phase with a master/slave clock type arrangement) - http://pqlit.eaton.com/ll_download_bylitcode.asp?doc_id=10925
We would like to connect our two UPS units together as at the moment one is a "cold" manual switch standby unit.
Do APC offer a synchronised phase output for N+1 redundancy between chassis and if so are there any special units required to join the outputs or can a standard tie-cabinet be used?
APC's docs aren't so clear on connecting modular (symmetra) UPSes to a common output. http://www.apcmedia.com/salestools/LARD-8YPBGX/LARD-8YPBGX_R0_EN.pdf
