Installation Guidelines

• Power Down: Always ensure the control system is powered down before installing or removing the terminal board or associated I/O packs.
• Mounting: Secure the board using the provided sheet metal carrier. Ensure the plastic insulator is correctly positioned to prevent short circuits against the cabinet backplane.
• I/O Pack Seating: When installing PDOA or YDOA packs, ensure they are fully seated into the H2A header. The mechanical connector force is designed to maintain integrity without additional fasteners.
• Wiring: Utilize the 48 terminal points according to the specific system wiring diagram. Ensure all field wiring is properly shielded and routed away from high-EMI sources to maintain signal integrity.
• ESD Handling: Handle the module using standard electrostatic discharge (ESD) prevention practices to avoid damage to internal SMT components.
