SITOP battery module, 24V/12Ah maintenance-free lead-acid, for SITOP DC UPS modules 6A/15A/40A.
The Siemens 6EP1935-6MF01 is a SITOP battery module with 24 V/12 Ah maintenance-free sealed lead-acid batteries, built to extend runtime on the SITOP DC UPS modules rated 6 A, 15 A and 40 A. It delivers up to 30 A in buffering mode and up to 30 A peak current, with a 20 A/32 V battery fuse for short-circuit protection and a maximum 3 A charging current.
This 12 Ah battery pairs with SITOP DC UPS modules across the 6 A, 15 A and 40 A range - verify buffering runtime against the connected UPS module's load rather than this module's 30 A output-current ceiling, which is a maximum, not a guaranteed runtime figure. The 20 A/32 V battery fuse and Class III protection rating fix the safety boundary for the pack itself, and wall or flat-surface keyhole mounting keeps the 9 kg pack out of the UPS module's own footprint. Service life drops from 4 years at 20 degC to 2 years at 30 degC, so ambient temperature at the installation site is the main variable to check before setting replacement intervals.
Used as the battery back-up stage in SITOP DC UPS installations protecting PLCs, drives and control panels through mains interruptions, where the 6 A, 15 A or 40 A UPS module handles power management and this module supplies the stored 24 V DC energy.

| ambient condition | For storage, mounting and operation of lead-acid batteries, the relevant DIN/VDE regulations or country-specific regulations (e.g. VDE 0510 Part 2/EN 50272-2) must be observed. You must ensure that the battery site is sufficiently ventilated. Possible sources of ignition must be at least 50 cm away. |

| note | Along with the storage and operating temperature, other factors such as the duration of the storage period and the charge status during storage have a decisive influence on the possible useful life. Batteries should therefore be stored as briefly as possible, always fully charged, and within the temperature range 0 to +20 °C. |
