Installation Guidelines
Ensure the PLC rack is powered down before inserting or removing the module to prevent electrical damage.
Install the module in an available slot within the Series 90-30 baseplate.
Use shielded twisted-pair cabling for RTD connections to minimize EMI/RFI interference.
Ensure proper grounding of cable shields at the module terminal block or designated ground point.
Verify that the module is configured correctly in the PLC software, specifically setting the %AI size to 6.
Maintain adequate ventilation around the PLC rack to ensure the ambient temperature remains within the 0 to 60 degC operating range.
