When mounting this board inside tight, sealed enclosures with poor ventilation, the ambient temperature must be verified to prevent the open collector circuit from shutting down under thermal over-stress.\u003c\/p\u003e\n\n\u003ch3\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h3\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1.5rem;\"\u003eTo eliminate electrical noise interference, verify that the open collector output lines utilize shielded, twisted-pair cabling. Ground the shield at the receiver (PLC\/Controller) end only. Additionally, verify that any inductive loads connected to the open collector output are suppressed with external diodes to protect the onboard switching components from back-EMF spikes.\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; color: #9b2c2c;\"\u003e\n  \u003cstrong\u003eCRITICAL WARNING:\u003c\/strong\u003e Prior to initiating installation or board extraction, ensure all main AC power lines feeding the instrument chassis are fully de-energized.
