This document provides a diagram and description of a machine terminal. The diagram shows the wiring connections between various components including sensors, circuit breakers, and disconnectors. Key components include channels 1-10 which connect to voltage transformers and current transformers, and status points for alarms, temperature sensors, and high-speed protection outputs. The diagram also indicates the connections for external controls of a disconnector labeled Q1.
