Installation Guidelines
Power Down: Always disconnect power from the PLC rack before inserting or removing the module to prevent electrical damage.
Mounting: Ensure the module is fully seated in the 90-30 baseplate slot and secured with the integrated locking screws.
Wiring: Use shielded twisted-pair cabling for analog signals to minimize EMI interference. Ensure the shield is grounded at the source end only.
Isolation: The module provides 1500V isolation; however, ensure external field wiring is routed away from high-voltage AC power lines.
Environment: Maintain ambient operating temperatures between 0 and 60 degC. Ensure adequate ventilation within the enclosure.
