Connecting SITOP UPS1100 battery modules to the UPS module

A maximum of 6 SITOP UPS1100 battery modules of the same type can be connected to a
UPS module.
The maximum permissible cable length between SITOP UPS1600 and battery module(s) is
3 m.
The cables and conductors used must be suitable 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 SITOP UPS1600 with 10 A or 20 A output current, use a minimum cross-section of
2.5 mm
• for SITOP UPS1600 with 40 A output current, use a minimum cross-section of 4 mm
For long cables, we recommend that this cross-section is increased to avoid nuisance alarms
when overload conditions occur during buffering.
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.
Material damage
It is not permissible that power terminals "BAT+" and "BAT-" are connected with "IN-", "OUT-"
or the 0V busbar.
