Am I correct, that you don't have a "Power Controller"? A DEC Power
Controller is a metal box with one line cord in and many jacks for plugging
in accessories, and a contactor (big relay) inside for switching many
of the jacks on/off under remote control of the 3-pin plugs/cables.
Without a Power Controller, you have no contactor, and no way of remotely
switching things on and off.
With such a small system, you can probably go to Radio Shack and get one
of their power controllers, that works by sensing current draw to one
of your boxes and turns the rest on when that one comes on. No, it's not
as fancy or as configurable as a DEC power controller, and Radio Shack
certainly doesn't have any versions that do 3-Phase at 60 Amps per phase,
but it ought to work fine for a small system like yours.
