Charger enclosure becomes very hot to the touch during normal charging, though charging continues.

Safety first: If the enclosure is too hot to touch comfortably, stop charging and turn off power at the breaker.

• Check installation environment: Ensure the charger is not installed in direct sun or near other heat sources. Provide shade or ventilation if needed.
• Inspect vents: Clear any dust or obstructions from ventilation openings.
• Internal terminal check: With power OFF, open the charger and tighten all power terminals (supply and output) to the torque specified in the Schneider manual.
• Assess cable size: Have an electrician verify that the supply cable cross-section matches the charger's rated current and installation length.
• Component evaluation: If overheating persists, a technician should inspect the contactor and internal wiring for discoloration and replace overheated components.
