Group We're designing a piece of mains powered IT equipment for use by the general public, that will be sold in a number of different countries.
The unit has a single DC-jack socket that can be connected to an external battery box. Whilst powered from the mains the unit will charge the battery and when mains fails it will accept power from the battery. we currently have " + -(o- - 12V 1A " above the socket - and there's not much room to add anything much bigger We wish to discourage users from plugging in an external dc supply ( from a solar panel for example) as the unit will not work off an external DC supply alone ( it will only start up from the mains). I'd welcome suggestions as to the best way to label the socket. regards Charlie Blackham Approvals Manager Airspan Communications Ltd
