FAQs
The OS306U-W is designed for no-neutral operation. Follow the included wiring diagram, connect the two wire leads to line and load per the selected configuration, and cap any unused conductors. Ensure the box has a proper line and load path, and adhere to electrical codes. This approach reduces install time and wiring changes in retrofit environments.
The device supports multiple lamp types, including MLV, FLR, LED, CFL, HAL, INC, and ELV, with a 600 W maximum load. Verify compatibility with your specific fixtures and drivers, especially LED and CFL drivers, to ensure stable operation and avoid nuisance tripping or flicker.
Yes, the OS306U-W supports both 1-pole and 3-way configurations. For multi-switch control, pair it with compatible companion switches and follow the manufacturer wiring diagrams. This provides flexible control across larger rooms while preserving occupancy sensing functionality.
The OS306U-W is NOM certified and cULus Listed, signaling compliance with relevant safety and electrical standards. These certifications support use in many commercial installations and can simplify regulatory approvals during site audits.
Expect energy savings from automatic lighting control in unoccupied periods, contributing to faster payback. Maintenance needs are low due to solid-state sensors and long service life. The no-neutral design also reduces wiring changes during upgrades, further enhancing lifecycle value in corporate facilities.
