          PRODUCT DESCRIPTION

          6SL3210-1KE21-3UF1 G120C 5.5 kW Compact Inverter

          Siemens 6SL3210-1KE21-3UF1 is an unfiltered SINAMICS G120C compact inverter for three-phase 380 to 480 V supplies. At 400 V it is rated 5.5 kW in low-overload duty and 4.0 kW in high-overload duty. The corresponding output currents are 12.50 A and 8.80 A, with a maximum output current of 17.60 A. PROFINET and EtherNet/IP provide the network connection.

          The FSB enclosure combines the control electronics and power stage with fan cooling, six standard digital inputs, one fail-safe input, relay and transistor outputs, and analog interfaces. A 4 kHz pulse frequency is specified; the output range extends to 550 Hz with V/f control or 240 Hz with vector control. The IP20 assembly permits shielded motor cables up to 50 m or unshielded cables up to 150 m under the stated installation conditions.

          SYSTEM & REPLACEMENT CHECK

          Information needed before ordering

          Three direct checks to secure your system integration and minimize ordering risks.

          System integration Replacement check Manuals & support
          SYSTEM INTEGRATION

          Integrate 6SL3210-1KE21-3UF1 within SINAMICS G120C

          Select the overload duty before setting the motor data and input protection. The 400 V low-overload rating is 5.5 kW at 12.50 A output, whereas high-overload duty is 4.0 kW at 8.80 A. The rated input currents also differ, so feeder sizing must use the selected duty rather than the maximum output-current figure.
          Configure the required PROFINET or EtherNet/IP connection together with the local digital and analog signal assignments. The unfiltered version does not include a line EMC filter. Provide the external EMC measures required by the installation, bond the protective earth, and observe the 50 m shielded or 150 m unshielded motor-cable limits.
          Allow the integrated fan to maintain the specified airflow and keep the operating ambient within -10 to 40 degrees C for the stated ratings. Commission the selected V/f or sensorless vector mode using the motor nameplate data. The published vector frequency ceiling of 240 Hz is different from the 550 Hz V/f ceiling.

          Features:

          • Line supply: 3 AC 380 to 480 V; +10% / -20%
          • Line frequency: 47 to 63 Hz
          • SINAMICS G120C
          Use 6SL3210-1KE21-3UF1 only within the documented SINAMICS G120C arrangement and applicable installation instructions.
          INTERCHANGEABILITY

          Replace 6SL3210-1KE21-3UF1 within SINAMICS G120C

          Record the full 6SL3210-1KE21-3UF1 order code, overload selection, motor data and network settings before exchanging the inverter. Preserve the unfiltered variant and FSB mechanical arrangement; a filtered or differently rated G120C must not be treated as an identical replacement.
          Isolate the supply, follow the Siemens DC-link discharge procedure, and verify the absence of hazardous voltage before disconnecting terminals. Identify the line, motor, braking and protective-earth connections separately. Retain the signal assignments and network configuration for the replacement unit.
          Restore parameters using a compatible commissioning procedure and check both the motor direction and commanded speed under controlled conditions. Confirm the selected current limits, network status and cooling operation before returning the process to service. A valid power rating alone does not establish parameter compatibility.
