Connection X1
The connections "X1+" and "X1-" are used to transfer power between the SITOP UPS1600
and the SITOP UPS1100.
1. Ensure that the cables are dimensioned corresponding to the fuses in the
SITOP UPS1100 and the impedances between SITOP UPS1600 and SITOP UPS1100
are the same.
2. Only connect charged batteries with one another.
Connection X2
Connections "X2-1" and "X2-2" serve to transfer data between SITOP UPS1600 and
SITOP UPS1100 (see Figure Wiring (Page 204)).
When several battery modules are used, note the following:
● Up to 6 battery modules of the same type can be connected together in parallel.
● If different battery modules are connected in parallel, the relay REL2 is energized and de-
energized at regular intervals (battery defective). No calculations with regard to charge
and remaining buffer time are performed. The battery modules are not charged, but
buffering is possible.
● If more than 6 battery modules are connected in parallel, the relay REL2 is energized and
de-energized at regular intervals (battery defective). No calculations with regard to charge
and remaining buffer time are performed. Charging and buffering, however, is possible.
