Introduction to the 6EP1935-6MF01
When an unexpected power outage threatens production uptime, the 6EP1935-6MF01 from Siemens delivers dependable backup power. This SITOP battery module uses service-free sealed lead-acid batteries to support SITOP DC UPS modules rated for 6 A, 15 A, and 40 A. Designed for industrial environments, it ensures your critical controls keep running when the mains supply fails.
Key Features and Technical Specifications
The 6EP1935-6MF01 is engineered for performance and longevity. Its key specifications include:
- Nominal voltage: 24 V DC
- Capacity: 12 Ah
- End-of-charge voltage (at 20 °C): 27.3 V
- Maximum permissible charging current: 3 A
- Battery fuse: 20 A / 32 V (solid-state circuitry blade-type fuse)
- Protection class: Class III
- Degree of protection: IP00
- Ambient temperature (operation): -15 ... +50 °C
- Dimensions (W x H x D): 253 mm x 168 mm x 121 mm
- Weight: approx. 9 kg
These specifications directly influence total cost of ownership. For example, the temperature-compensated charging voltage (27.8 V at 10 °C down to 26.3 V at 50 °C) optimizes battery life, reducing replacement frequency and lowering long-term expenses.
Applications and Use Cases
This battery module suits applications where uninterrupted DC power is essential. Use it in PLC systems, process controls, and safety-related circuits that require ride-through during brief outages. Because it pairs with SITOP DC UPS modules, it provides seamless transition to battery power, protecting your processes from costly interruptions. The module’s sealed design also makes it suitable for installations where maintenance access is limited.
Installation and Setup
Mounting the 6EP1935-6MF01 is straightforward. It can be screwed onto a flat surface using keyhole mounting for M4 screws. The spring-loaded terminals accept 0.08 ... 4 mm² wires for the +BATT and -BATT connections. Ensure adequate ventilation around the battery site, and keep potential ignition sources at least 50 cm away, as per the operating notes.
Maintenance and Reliability
Routine care is minimal because the batteries are service-free. However, environmental temperature significantly affects service life. At 20 °C, the battery typically lasts 4 years; at 30 °C, 2 years; at 40 °C, 1 year; and at 50 °C, only 0.5 years. To maximize ROI, install the module in a cool, controlled environment. Also, for storage, keep batteries fully charged and within 0 to +20 °C to preserve capacity.
Compatibility and Integration
The 6EP1935-6MF01 is specifically designed for SITOP DC UPS modules with ratings of 6 A, 15 A, and 40 A. It connects via screw terminals for reliable power transfer. Always verify compatibility with your specific UPS model before installation.
Troubleshooting and Common Issues
If the UPS does not provide backup power, check the battery fuse first. The module includes a 20 A/32 V solid-state fuse that protects against short circuits. Also, verify the charging voltage is within the recommended range for your ambient temperature. If the battery seems weak, measure the open-circuit voltage; a fully charged battery should read near 27.3 V at 20 °C.
