Is the metal cover on the output terminal safe?

Yes, it is perfectly safe. The power supply's chassis is made of metal and is securely grounded. As the metal terminal cover is attached to the chassis, it shares the same ground connection, ensuring user safety. For models with bus bar terminals, the interior of the cover is electrically insulated to prevent the metal exterior from making contact with any live copper terminals.
