Additionally, ensure that a minimum of 50 mm of vertical clearance is maintained above and below the rack within the enclosure to facilitate adequate natural convection cooling, as excessive heat buildup can degrade internal capacitor lifespans.\u003c\/p\u003e\n\n\u003ch3\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h3\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eWhen connecting the RS-232C port to an external HMI or third-party device, ensure the cable shielding is tied directly to the functional ground (GR) terminal on the CS1 backplane power supply. Do not loop ground wires back to signal common (SG) terminals on the port, as this introduces common-mode noise that can interrupt serial communications during inductive switching events nearby.\u003c\/p\u003e\n\n\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\n\u003cdiv style=\"background-color: #fff5f5; border-left: 4px solid #c53030; padding: 15px; margin-bottom: 1.5rem;\"\u003e\n  \u003cstrong style=\"color: #9b2c2c; display: block; margin-bottom: 0.5rem;\"\u003eCRITICAL WARNING: ELECTRICAL SHOCK \u0026amp; SYSTEM DAMAGE RISK\u003c\/strong\u003e\n  \u003cp style=\"color: #9b2c2c; margin: 0;\"\u003eDisconnect all AC\/DC power sources feeding the PLC rack, field devices, and adjacent machinery before mounting or removing the CPU unit.
