The terminal block of an I/O Unit can be removed by loosening the mounting
screws. You do not have to remove the lead wires from the terminal block in or-
der to remove the block from an I/O Unit.
Do not wire voltage inputs as shown on the left below.
When two-wire sensors, such as photoelectric sensors, proximity sensors or
limit switches with indicators are connected to the PC as input devices, the input
bit may be turned ON erroneously by leakage current. In order to prevent this,
connect a bleeder resistor across the input to reduce the input impedance.

Terminal block mounting screws
Loosen the terminal block mounting screws to remove
the terminal block from the I/O Unit. Make sure the
mounting screws on the terminal block are tightened af-
ter wiring is complete and the terminal block is re-
mounted to the I/O Unit.
