FIRE HAZARD |
|
Use only the correct wire sizes for the current capacity of the power supplies. |
|
Failure to follow these instructions will result in death or serious injury. |

|
|
UNINTENDED EQUIPMENT OPERATION |
|
Do not exceed any of the rated values specified in the environmental and electrical characteristics tables. |
|
Failure to follow these instructions can result in death, serious injury, or equipment damage. |

1 Best engineering practices usually require a single wire connected to each terminal, or two wires if an appropriate cable end is used. Connection of more than two wires may require the application of external terminal blocks (verify local codes and regulations that may apply). |

The wiring diagram for the Fast inputs is same as that of the digital inputs.
