DC Power connector type on FG - 60F / 80F ?

Hello,

I'm hoping to find any information on the type of connector used on the end of the AC/DC power supply provided with these firewalls.

We have our own fully redundant DC power plant at some sites that we'd like to connect directly to 12VDC without the need for the AC adapter - doesnt make sense for us to go from AC->RedundantDC->Inverter->AC-adapter->FG60F.

We'd like to source our own part so that we can go AC->RedundantDC->12V->FG60F
