3-3-4 Wiring Methods
Either make a cable using the special connector (purchased separately), or
connect to a terminal block using an OMRON special cable with a connector.
Note (1) Do not apply voltages that exceed the maximum switching capacity of
output circuits and the input voltage of I/O circuits.
(2) Do not mistake positive and negative when wiring power supply, where
there are positive and negative terminals.
(3) To conform to the EC Low Voltage Directive, use a DC power supply for
I/O that has reinforced or double insulation.
(4) Check that the connector wiring has been performed correctly before
supplying power.
(5) Do not pull on cables. Doing so may result in disconnection.
(6) Do not bend cables beyond their natural limit. Doing so may result in dis-
connection.
