FAQ

What kind of battery module is compatible with this 6EP1931-2FC01 UPS?

This module is designed to work with Siemens SITOP lead-acid battery modules. The required battery capacity depends on the desired backup time and load current.

No, the 6EP1931-2FC01 is not designed for direct parallel connection to increase current capacity. For higher current requirements, a higher-rated UPS module should be selected.

The DIP switches are used to configure alarm settings and operating modes, such as enabling or disabling specific alarms (o.k., BAT) and setting the ON/OFF state.
