The Bosch Rexroth drive control MPN R911200499 (RD51.1-5B-018-L-C1-FW) is designed for use with industrial machinery and operates at a nominal connecting voltage of 3 x 500 V AC (+/-10%) with a rated power output of 18 kW and a rated current of 24 A. It is classified as environmental class 3K3 according to DIN IEC 721-3-3. The unit features a built-in brake chopper and supports external 24 V standby power, as well as RZC01.1-XN module connection. Safety measures include mandatory protective conductor connection, use of an isolation switch for emergencies due to leakage current exceeding 3.5 mA, and prevention of contact with live parts. The housing may become hot during operation; only qualified personnel should handle the device. Forced air cooling is implemented, and installation requires a 22.5 mm mechanical grid pattern, sufficient airflow, and adherence to a maximum relative humidity of 90% without condensation. EMC compliance must be ensured during integration. Factory-assigned firmware is provided.
