Field Installation Guidelines

1. Verify identification: Check the model, serial number, manufacturing location, and manufacturing date on the product label.
2. Confirm hardware compatibility: Match the termination block to the intended I/O card using the DeltaV hardware documentation.
3. Set rotary keys: Configure the keying mechanism for the designated I/O card before installation.
4. Inspect wiring: Use the wiring diagram on the left side of the card to verify terminal assignments and field connections.
5. Observe hazardous-area procedures: Follow DeltaV Zone 2 installation instructions in document 12P2046 where applicable. Isolate power and follow site safety procedures before installation or removal.
6. Maintain environmental limits: Keep operation within 0 to 70 deg C and 5 to 95% non-condensing relative humidity. Observe the specified shock, vibration, contamination, and IP20 limitations.
