Installation Guidelines
- Ensure the system power is fully disconnected before installing or removing the module from the chassis.
- Handle the module using proper ESD (Electrostatic Discharge) mitigation techniques to prevent damage to internal circuitry.
- Use shielded twisted-pair cabling for all analog inputs to minimize EMI/RFI interference.
- Maintain proper ground connections for the chassis to ensure effective common mode noise suppression.
- Check that input signal wiring does not exceed the +/- 30V maximum input voltage threshold to avoid hardware failure.
- Verify that the module is firmly seated in the rack to maintain secure electrical contact with the backplane.
