Field Installation Guidelines

• Verify module compatibility with the target Yokogawa CPU before installation.
• Install the module with system power removed unless the host platform documentation explicitly permits online replacement.
• Use IEEE 802.3 compliant Ethernet cabling appropriate for the selected network speed.
• Maintain cable separation from high-voltage and high-current conductors to reduce electromagnetic interference.
• Terminate cable shields according to the site grounding standard and avoid multiple uncontrolled shield grounding points.
• Confirm network addressing and protocol configuration before connecting the module to an active control network.
• After installation, verify link status and network communication with connected nodes before commissioning.
