FAQs
Begin by confirming the primary connection for 480 V delta and the secondary output of 208Y/120 V. Mount the unit on a level surface within the FR939 frame, ensure proper clearance, and connect the primary leads to the 480 V sources. Verify the secondary connections to 208Y/120 V loads, secure all terminations to torque specs, and use the NEMA 2 enclosure as designed. For best results, follow the manufacturer’s installation notes and perform a final insulation and insulation resistance check before energizing.
