12 V to 30 V
CAUTION: The power supply 0 V should be terminated at the machine ground ("star point").
A negative supply can be used when wired appropriately.
NOTES:
A switch can be fitted between the machine power supply and the red wire, to aid powering up the RMI-Q when
partnering.
Inputs P2–P4 are the difference between RMI and RMI-Q wiring, as these inputs allow multiple radio probes or tool
setters to be used.
