Figure 7-6
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
• for a 40 A system, a minimum cross-section of 4 mm
• when connecting the SITOP BAT1600 38 Ah battery module, the minimum cross-section is
6 mm
Longer cable lengths or smaller cross-sections can result in nuisance alarms when buffering!
When several battery modules are used, note the following:
When connecting several battery modules in parallel (max. 6) the following applies:
1. Ensure that the battery modules are the same type and have the same charge state.
2. Battery modules are wired to the UPS in a star configuration with the same cable lengths
(ensure that the impedance is the same for all cables).
3. Dimension the cross-section of the star configuration wiring for the total current (if required,
reduce all fuse values).
