The 5 kWs energy content (stored in capacitors, not batteries) provides ride-through for short mains dips or supports an orderly controlled shutdown of the connected load, with the UPS500S managing the DC bus and the expansion module adding the extra capacitance. The enclosure measures 125 mm high, 70 mm wide, and 125 mm deep, with IP20 protection — it occupies a standard DIN-rail footprint and snaps onto a 35x7.5/15 mm rail per EN 60715. Mounting clearances: 50 mm required above and below the module for airflow and wiring access; no side clearance needed (0 mm left/right). Screw-type terminals handle the field wiring; the housing can be lined up with adjacent SITOP units for a clean panel layout. ## Environmental and reliability ratings Operates from 0 to 60 °C with natural convection (no fan needed), and can be stored or transported from -40 to +70 °C. MTBF at 40 °C is 350,000 hours, reflecting the capacitor-based design with no wear-limited battery cells. Rated for environmental category 3K3 per IEC 60721 (5 to 95% humidity, no condensation), and classified as operating resource protection class III. The SITOP UPS501S is the expansion module for the UPS500S family — no direct replacement or second-source cross-reference exists in the SITOP line; the 6EP1935-5PG01 is the specific order code for the 5 kWs variant.","metaTitle":"Siemens 6EP1935-5PG01 SITOP UPS501S Expansion Module, 5 kWs","metaDescription":"Siemens 6EP1935-5PG01 SITOP UPS501S expansion module, 5 kWs energy storage for UPS500S.
