to “On” (Close), until the equipment prompts you during the startup procedure
via the display, because it can cause irreversible damage to the equipment or
accidents because the engineer is exposed to eleCTrICal DIsCHarGe
DanGers. The UPs prompts before connection with the battery cabinet.
UPs connection with battery pack will be implemented with the supplied trunk
cable by connecting one side to terminals
(X11), (X23)
and
(X12)
of the UPs and
the other one to terminals
(X47)

(X49)
and
(X48)
on the battery pack. always
respect the stated polarity in the labeling of each part and in this manual. The
color of the cables (red for positive, black for negative, blue for middle tap (n)
and green-yellow for earth bonding), see Fig. 20.
Turn off multiple battery packs in parallel. Firstly connect the black wire from the
negative terminal of the UPs to the negative terminal of the first battery pack and
then from there to the others. Proceed with the cables (positive: red, center tap:
blue, protective earth, green-yellow) accordingly.

If after starting up the UPs, it is required to
disconnect the battery cabinet, the equipment has to be completely shutdown
(see section 5.2). Turn off the battery fuse holder switch
(Q8)
located in the battery
