How to install King 36V 400W Outdoor PSU
- Plan the system layout. King Permanent Lighting installs follow a layout-first pattern. Sketch the eave line, PSU location, controller location, and accessory placement before any wire pulls.
- Mount in the rated enclosure. PSU and controller units mount inside the King Permanent outdoor enclosure box for code-compliant install. GFCI outlet required for the supply.
- Route low-voltage wire through protective loom. Use the King Permanent protective loom along the run. Bury or tuck behind soffit where the wire isn't architecturally visible.
- Connect with King proprietary connectors. Don't splice with generic wire nuts. Use the King 3-wire connectors at every junction.
- Commission via the King controller app. Pair the controller via Bluetooth + Wi-Fi. Run a full color cycle to confirm every LED is firing before final mount.
