The two units are completely different; the 675 is a small 1U single AC 
device that can only provide power to one of its six outputs at a time. 
The RPS connectors are also physically incompatible.

It also has a nasty "feature" of not letting the connected device fall 
back to its internal power supply, so you can't use it to provide dual 
AC inputs and run a device from RPS-only like you can with the 600. 
(Although someone said if you pull the plug on it rather than press the 
button on the front that it will, but I haven't tried that with mine.) 
It's purely a standby power source.
