+**WARNING**: I just discovered that the 082SM ("M" for "medical") has small tabs on both sides of
+the inlet (**not** shown in the datasheet). These tabs physically prevent normal C13 power
+cords (what the Brits would call "bog standard kettle cords") from fitting into the
+receptacle. I _think_ but am not yet sure that the 082S (general purpose model)
+does not have the tabs (I think they are to prevent non-certified
+cords from being used accidentally). I've ordered an 082S to verify and will
+update this README once I've confirmed.
+
+Also, as should be obvious: You will need to acquire and insert 250VAC buss
+fuses (by pulling out the little drawer — there is a slot for the active
+fuse, plus room for a spare in the front).
