Selection Guide
Use the following criteria to select the correct capacitor module for your SINAMICS S120 system:
- Step 1 – Determine DC bus voltage: Confirm your system operates at ≤600 V DC (standard European 3-phase supply).
- Step 2 – Calculate required capacitance: Sum the motor module capacitance requirements; select a module that bridges the gap to your ride-through target.
- Step 3 – Verify booksize format: 6SL3100-1CE14-0AA0 is booksize only — confirm your Line Module and Motor Modules are also booksize.
- Step 4 – Check available DIN rail / cabinet space: Module width is fixed; plan cabinet layout accordingly.
- Step 5 – Confirm firmware version: Ensure SINAMICS S120 firmware supports the capacitor module (V4.x and above recommended).

Replacement & Compatibility FAQ
Q: Can I use 6SL3100-1CE21-0AA0 as a direct replacement for 6SL3100-1CE14-0AA0?
A: Yes, in most cases. The -1CE21 offers higher capacitance and is physically compatible with the same booksize slot. Verify your system’s total DC bus capacitance budget does not exceed Line Module limits.
Q: Is this module compatible with SINAMICS S120 chassis format?
A: No. The 6SL3100-1CE14-0AA0 is designed exclusively for the booksize format. Chassis-format systems require different capacitor modules.
Q: Can third-party capacitor modules replace this unit?
A: Third-party alternatives exist but may not support DRIVE-CLiQ communication or Siemens diagnostics. Contact Konmask for vetted alternatives.
Q: What is the typical service life of this capacitor module?
A: Electrolytic capacitors typically have a service life of 5–8 years depending on operating temperature and duty cycle. Siemens recommends periodic capacitance testing.
Q: Do you provide warranty on used or refurbished units?
A: Yes — Konmask offers a 90-day functional warranty on all tested surplus units, and full OEM warranty on new stock.
