The Bosch Rexroth MPN R911200283 (RD52.1-4B-004-P-NN-FW) is a drive control unit featuring field-oriented vector control. It operates at a nominal connecting voltage of 3 x 380VAC to 480VAC (±10%) and is designed for integration with 4 kW motors. This converter includes a built-in brake chopper and utilizes a heat dissipation panel for cooling. Electrical connections must be safely isolated; terminals with voltages from 5V to 50V must comply with IEC 60364-4-41 standards. Installation requires a protective conductor according to the appropriate wiring diagram, and a start-inhibit or emergency stop circuit is required to ensure safe isolation from power during maintenance. The device should be installed perpendicularly within a closed cabinet, with sufficient clearance, and should not be operated in environments with condensation, elevated ambient temperatures, or in proximity to remote-control or high-frequency equipment. Leakage current exceeds 3.5 mA.
