FAQs
To install the SFS5P-A, mount the device flush in a compatible enclosure, route conductors to the back and side terminals as labeled, and secure with the provided fasteners. Ensure the panel ground is connected and the live/neutral conductors align with the wiring diagram. This approach minimizes enclosure protrusion and helps maintain a clean, serviceable panel. In practice, double-check the torque for the lbf-inch rating and verify proper insulation on all connections prior to power-up.
The SFS5P-A supports single-pole and three-way configurations, enabling multi-location control for the same fan circuit. This is advantageous in larger facilities or equipment with distributed control points. It allows consistent fan speed modulation across locations while preserving wiring simplicity. When designing a system, plan the control wiring to minimize cross-talk and ensure that remotes and local controllers share a common neutral and line reference as per the installation sheet.
Yes. The SFS5P-A is cULus Listed, indicating compliance with applicable North American safety standards for electrical devices used in fan control. This certification supports code conformity during inspections and assists procurement teams in meeting regulatory requirements. As with any installation, verify local amendments and ensure proper enclosure protection, wiring methods, and labeling are in place for ongoing compliance.
Key ratings include 120 V supply, 60 Hz frequency, single-phase operation, and a torque rating of 14 lbf-in to ensure reliable actuator performance. The device is designed for fan loads with back and side wiring and flush mounting. It supports both single-pole and three-way wiring schemes, making it suitable for standard HVAC fans and smaller process cooling fans in industrial environments.
Retrofitting with the SFS5P-A can reduce installation time thanks to no-neutral operation and flexible wiring, lowering labor costs. The device’s solid construction (polycarbonate enclosure) and cULus safety certification support longer service life and fewer regulatory headaches. Additionally, improved speed control efficiency translates to energy savings and potentially lower operating costs over the fan’s life, delivering measurable return in maintenance budgets.
