FAQs
Installation should follow the specified instruction sheets and regional codes. Use the flush ceiling mount to maximize clearance, ensure wiring within the 347–480 VAC, 50/60 Hz supply, and verify the area classification (Hazardous/Classified Locations) before mounting. Confirm a proper 4X enclosure fit and use copper-free aluminum components to resist corrosion in harsh environments. Refer to IF 1947 installation sheets for backup guidance.
The provided data does not indicate dimming capability. The fixture is specified for 347–480 VAC operation with a PF greater than 0.98, suitable for steady-state non-dimmable installations. If dimming is required, consult Eaton’s spec guides or contact an Eaton representative to confirm compatible dimming drivers or retrofit options.
