This versatile approach caters to varying installation requirements, offering options for both DIN rail and cabinet-based setups.
- Terminal Block Wiring: The contact inputs are directly wired to the terminal block, commonly utilizing 18 AWG wires for optimal connectivity and signal transmission. This wiring setup ensures reliable and efficient signal transfer between the input sources and the terminal board, facilitating seamless functionality within the system.
- Shield Termination: To maintain proper shielding and minimize interference, shields associated with the wiring should be appropriately terminated. It's recommended to terminate these shields on a separate bracket, thereby enhancing the overall integrity of the system and mitigating potential signal disruptions or electromagnetic interference.
- Chassis Grounding and SCOM: Notably, within the SCOM (Supervisory Control and Data Acquisition) framework, there are designated chassis grounding screws E1 and E2 that serve the purpose of grounding. These screws play a critical role in establishing a stable and secure grounding connection for the board, ensuring the integrity of the system's electrical grounding and enhancing overall safety measures.
- Maintenance and Safety Considerations: During installation and subsequent maintenance procedures, it's imperative to adhere to safety protocols and guidelines outlined in the provided documentation. Ensuring proper grounding, following recommended wiring practices, and taking necessary precautions are fundamental to maintaining system functionality and operator safety.
