🚫 What NEVER to Do (Common Misuse Warnings)

⚠️ Operating the power supply on the mains with the voltage selector in the wrong position (e.g., 110V on a 220V system).
err_01
Consequence: This can cause immediate internal damage to the power supply, such as component burnout.
✓ How to avoid: Always check and set the voltage selector to the correct voltage for your electrical system BEFORE connecting the power cord. Note: Standard US wall outlets supply 120V. This 220V-240V appliance requires a dedicated 220V-240V outlet or a high-wattage step-up voltage converter to operate in the US.
