RMI-QE basics
CAUTIONS:
Power supply voltage
Do not exceed 30 V between: the black wire and the screen wire (green/yellow); the red wire and
screen wire (green/yellow); or the red and black wires (power supply),
as this could result in permanent
damage to the RMI-QE and/or the customer power supply.
The use of in-line fuses at the machine cabinet end is recommended to provide protection for the
RMI-QE and cable.
Screen connection
A good connection must be made to machine ground (“star point”).
Output stage circuit
Ensure that outputs from the RMI-QE do not exceed specified current ratings.
