4.2 INSTALLATION: PARALLEL UPS
–
TERMINAL BLOCK
OPTIMA T10 & RT10 UPS allow connection in parallel up to 3 units. A system based on parallel UPS could offer a more reliable protection
for the load in case it is dimensioned to work as redundant system. Parallel connection also allows system can grow in power by adding
extra units.
For working parallel as a parallel system, all units must share same AC input and AC output. Some control cables must be also connected
between units of the system so that UPS will be able to know important information to share the load efficiently.
All input and output lines must have their own breakers (one per UPS) for safety reasons and for allowing isolation of any UPS when
required.
