• [ ] Isolate power: The 3RT841B controls motors up to several kW (depending on utilization category). Disconnect the main supply and auxiliary circuits. Lock-out/Tag-out (LOTO).
• [ ] Identify exact firmware version: Look at the label on the side of the device. There may be a “FW” or “Version” field. Current versions often range from V1.x to V3.x.
• [ ] Check compatibility: Does the new firmware require a different base unit or communication module? Consult SIEMENS Industry Online Support (SIOS).
• [ ] Backup parameters: Use Siemens parameterization software (described below) to save all existing settings (trip class, rated current, phase failure sensitivity).
• [ ] Stable power for the electronics: The 3RT841B’s electronics are typically powered via the control voltage (e.g., 24V DC or 110V AC). Ensure this remains stable during the update – use a UPS if necessary.
