It is recommended to leave a 1U ventilation gap above the rack enclosure if the average ambient operating environment continuously exceeds 40 degC. Ensure that end-of-line (EOL) monitoring resistors match the exact electrical profile specified by the field detectors to prevent persistent, false open-circuit fault codes on the active channels.\u003c\/p\u003e\n\n\u003ch4 style=\"color: #1a365d; margin-top: 1rem; margin-bottom: 0.5rem;\"\u003eCommissioning \u0026amp; Wiring Tips\u003c\/h4\u003e\n\u003cp style=\"color: #2d3748; margin-bottom: 1rem;\"\u003eTo minimize high-frequency noise interference from nearby variable frequency drives (VFDs) or heavy electrical switchgear, always route conventional zone loops using shielded, twisted-pair cabling. Ground the shield exclusively at the system rack end. When commissioning the 3-function remote input, verify that the total loop resistance of the control switch does not exceed 50 ohms, ensuring rapid signal execution without attenuation.\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;\"\u003eDisconnect all primary AC and DC power supplies before inserting or extracting the 5704F module.
