I?m pretty sure an RP06 requires 3 phase power, and chances are the same goes for RP04,
RP05 and perhaps RM02/03. The manuals would say, of course.
I remember that the RP06 or its brothers uses 3 phase power because of warnings that the
phases have to be hooked up right or the pack will unscrew at powerup (due to spinning in
the wrong direction).

There are only a VERY few devices that can be connected to a PDP-11
that need 3-phase power. One I know of is the RP07, but that is
really a VAX peripheral. Since it is Massbus, it COULD be connected to
an 11/70, though. Possibly also the RP06 might also be 3-phase.
