🚫 What NEVER to Do (Common Misuse Warnings)

⚠️ Connecting the power supply to the incorrect voltage (if not auto-switching) or with reversed polarity.
err_01
Consequence: Immediate damage to the power supply or the connected equipment.
✓ How to avoid: Always check the mains voltage and the correct polarity of the connectors before plugging in. 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.

⚙️ Hardware Setup, Adjustments & FAQs

❓ How do I know if the power supply is auto-switching or if I need to adjust a switch? cfg_01
Check the power supply's label. If it indicates '100-240V AC' without a visible selector, it's automatic. If there is a selector switch, set it according to your outlet's voltage before connecting.
