Safety Notes Setup / See notes in sections "Setup" and "Installation/Removal!" Installation Startup / Check whether the direction of rotation is correct in decoupled status (also listen out for Operation unusual grinding noises as the shaft rotates). Secure the shaft keys for test mode without output elements. Do not render monitoring and protection equipment inoperative even for test mode.
