3. Installation and Connection
Terminal block connector

Interface cable

Use a shielded cable such as that shown in the figure for the interface cable connected to the terminal block
connector. Connect the shield to the casing near the terminal block connector. In addition, connect the COM
terminal separately from the shield. (This cable should be prepared separately by the customer.)

To internal circuits
When using the general-purpose output as the reference point output, time until the output signal changes to
High is 200 ms after going past the reference point.
