7.3 Connecting SITOP BAT1600 battery modules to the UPS module
Up to 6 SITOP BAT1600 battery modules of the same type can be connected in parallel to a
UPS in a star topology.
The maximum permissible cable length between a UPS module and each battery module is
3 m.
The cables and conductors used must be approved for temperatures of at least 60/75 °C.
Note
Use the following minimum cross
-sections for the connecting cables/conductors (terminals
"+" and "
-") between the UPS module and battery module(s):
•
for a 10 A / 20 A system, a minimum cross-section of 2.5 mm
2
.
•
for a 40 A system, a minimum cross-section of 4 mm
2
.
•
when connecting the SITOP BAT1600 38 Ah battery module, the minimum cross-
section is
6 mm
2
.
Longer cable lengths or smaller cross-sections can result in nuisance alarms when buffering!
WARNING
The following precautionary measures should be carefully taken into account when working
with the battery module and the batteries:
1. Remove watches, rings and other metal objects.
2.
Always used tools with insulated handles.
WARNING
Material damage
It is not permissible that power terminals "+" and "-" are connected to "0V", "GROUND" or the
0V busbar.
