3. Key Features & Standards
- Modular Design: Works with G120 Control Units (CU240B/E-2, CU250S-2)
- Built-in Filter & Chopper: Reduces cabinet space, simplifies wiring
- Overload & Thermal Protection: I²t motor protection, overtemperature shutdown
- EMC Compliance: CE, cULus, RCM (C-Tick), SEMI F47, RoHS
- Communication: DRIVE-CLiQ (to CU), STO, digital I/O, braking resistor interface

4. Installation & Application Notes
- Mount vertically (top/bottom airflow) in a ventilated cabinet; clearances per Siemens manual
- Derate for high altitude, high ambient temp, or continuous overload
- Braking resistor sizing: use Siemens G120 sizing tool for dynamic braking
- Use shielded motor cable for EMC; bond shield at both ends
- Match to CU with matching firmware version; update if needed
- Technical data subject to change; always verify with latest official docs
