This document provides safety instructions and technical details for ABB RDCU Drive Control Units. Safety instructions include not working on a powered drive, waiting 5 minutes for capacitor discharge after switching off the mains, avoiding touching the circuit board to prevent static - damage, and not using excessive force when detaching connectors or covers. Before installation, check the RDCU unit's application program and device type against the converter hardware. The unit has various input and output interfaces such as analogue outputs (X21), digital inputs (X22), 24 VDC power output (X23), relay outputs (X25 - X27), and multiple slots for module connections. Technical data covers mounting, housing materials, connector types, voltage outputs, input specifications, and ambient conditions. It also mentions applicable standards for immunity, emission, and PELV requirements.
