RMIO Module Installation
The optional remote module (RMIO) is designed to be mounted near the motor. This
eliminates the need for multiple RTD cables to run back from the motor, which may be in a
remote location, to the switchgear.
Although the RMIO is internally shielded to minimize noise pickup and interference, it
should be mounted away from high current conductors or sources of strong magnetic
fields.
