2. Varnostne informacije

Please read and understand all safety instructions before operating the device. Failure to comply with these instructions may result in electric shock, fire, or damage to the product.

• Napajalnik vedno priključite na ozemljeno vtičnico.
• Ne delajte v mokrih ali damp pogojev.
• Zagotovite ustrezno prezračevanje, da preprečite pregrevanje. Ne blokirajte prezračevalnih odprtin.
• Ne odpirajte casing; v notranjosti ni delov, ki bi jih lahko uporabnik servisiral. Servisiranje prepustite usposobljenemu osebju.
• Preverite vnos voltage settings (110V/220V) match your local power supply before connecting.
• Use only the specified power cord and accessories.
• Disconnect power before making any connections or disconnections to the output terminals.
