Charger enclosure feels excessively hot to the touch during normal charging, even in mild ambient temperatures.

Safety first: Overheating can lead to fire. If the enclosure is too hot to touch comfortably, stop using the charger immediately.

• Check installation environment: Ensure the charger is not installed in direct sunlight without shading or in a confined, unventilated box.
• Inspect terminations (power off): Isolate power and check all high‑current terminals for tightness and signs of overheating (discolouration, melted insulation).
• Verify cable size: Confirm that the supply cable cross‑section meets Rolec’s specification for the charger’s current rating and run length.
• Check internal fan: On models with a fan, verify that it runs during charging. Replace if seized or noisy.
• Reduce load temporarily: If the charger allows current limiting, reduce the maximum current and monitor temperature while arranging a permanent fix.
