THE “DI” VERSION OF THE UPS SERIES HAS A BYPASS LINE SEPARATE FROM THE INPUT LINE.
The UPS series with Separate Bypass allows for making a separate connection between the input line and the bypass line.
The UPS output will be synchronised with the bypass line in such a way that there will not be any incorrect switching between
push-pull voltages if the automatic bypass intervenes or the maintenance bypass switch (SWMB) is closed.

PHASE INPUT
(“TM”
VERSIONS ONLY
)
THE “TM” VERSION OF THE UPS SERIES ALLOWS FOR INSTALLING A UPS POWERED BY A THREE-PHASE OR
SINGLE-PHASE LINE.
In the THREE-PHASE connection, the load current will be split between the three input phases; if the bypass intervenes or in
the bypass mode operation, all the load current will be absorbed by the “L1” input line.
