Charger starts charging then stops after a short time; LEDs indicate over‑temperature or thermal error

Safety: Turn OFF power before tightening any internal connections.

• Check installation location: Ensure the Grizzl‑E is mounted vertically on a solid surface with adequate airflow. Remove any objects blocking vents or covering the unit.
• Inspect for heat damage: After power is OFF and the unit has cooled, remove the cover and look for browned plastic, melted insulation, or a burnt smell near the contactor and terminal block.
• Tighten connections: Gently tighten line and load lugs on the contactor and terminal block to the specified torque. Loose connections can cause overheating.
• Monitor ambient temperature: If installed in a garage or enclosure that gets very hot, consider improving ventilation or shading.
• Persistent thermal error: If the unit trips even when cool and connections are sound, the internal temperature sensor or control board may be defective and require replacement.
