Ensure the standard spacing around the CT 370A rack mounting slot is clear to prevent thermal degradation of aging onboard passive components.\u003c\/p\u003e\n\n\u003ch4\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eAlways discharge any static electricity from your body or tools by utilizing a grounded ESD wrist strap before handling this module. Ensure the rack backplane connections are clean and free of oxides or debris before inserting the board. Never use excessive force; the module should slide smoothly into its corresponding guide rails and seat firmly into the backplane connectors.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cdiv style=\"background-color: #fff5f5; border-left: 4px solid #c53030; padding: 1rem; margin-bottom: 1.5rem;\"\u003e\n  \u003cp style=\"color: #9b2c2c; font-weight: bold; margin: 0 0 0.5rem 0;\"\u003eCRITICAL WARNING\u003c\/p\u003e\n  \u003cp style=\"color: #9b2c2c; margin: 0;\"\u003eThis module is NOT hot-swappable.
