"[...] it also needs to be disconnected from the batteries."
The KDF7 was a second-generation industrial control computer. It had a hefty Ni-Cd battery to keep it alive long enough for a tidy shut-down in case of a power failure. The battery terminals had large hex nuts to clamp the cable connectors. Unfortunately the spacing between the two terminals could be bridged with a spanner - which would then become welded to the terminals.
