Usage Notes / Installation Tips
- Install the transformer at least 12 inches above ground level; keep well ventilated and dry.
- Do not use with dimmers. Disconnect power before installation or wiring changes.
- For best performance, keep total load ≤ 80–90% of rated wattage; long cable runs increase voltage drop—use appropriate wire gauge.
- Balance load evenly across outputs when possible and ensure the photocell is not blocked by nearby light sources.
