Installation & Maintenance

For installation, ensure your cabinet meets standard ventilation requirements—typically around 50mm clearance on all sides. Wiring should follow local electrical codes, and we recommend using copper conductors only. Routine maintenance includes periodic cleaning to prevent dust buildup and firmware checks if integrated into smart systems. Calibration isn’t usually necessary unless operating outside recommended temperature ranges.

Quality & Certifications

This relay carries key certifications like CE, UL, and RoHS compliance, ensuring it adheres to global safety and environmental standards. The manufacturer offers a 12-month warranty, though failures are rare given its build quality. In most cases, customers find that the product exceeds expectations in terms of longevity and performance.
