    Correct power supply for PS30?

    I'm installing mine, and can't find any mention of the power supply cables in the manual.
    If I don't put a switch on it, will i have a draw?
    Or does the MFD switch it on/off?

    The PS30 (and PS31, PS60, PS21, and PS22) all use a special wire in the network cable to turn on the units from the MFD and draw no current when the MFD is off.
