Technical Questions

Q: What's the difference between fused and non-fused blocks?

A: The 140CFI00800 provides termination without fuses, suitable when external protection exists or fuse protection isn't required.

Q: Why four terminals per point for analog signals?

A: This allows connection of signal pairs, shields, and test points simultaneously for complete analog wiring solutions.

Q: Which analog modules work with this block?

A: Specifically designed for 140AVI03000 and 140ACI03000 analog input modules in Quantum systems.

Q: How should I store unused blocks?

A: Keep in original packaging in dry conditions to prevent corrosion and contamination of terminals.

Q: What wire preparation is recommended?

A: Use ferrules or proper stripping techniques to ensure reliable connections and prevent stray wires.
