Wiring Methods
To connect to a Terminal Block, use an OMRON Cable preassembled with the
special connector or attach the special connector (sold separately) to a cable
yourself.
Note
1.
Do not supply a voltage to the input terminals that exceeds the I/O circuit's
specified input voltage range. Likewise, do not connect a voltage or load
that exceeds the output circuit's max. switching capacity.
2.
When the power supply terminals are marked with + and
−
indicators, verify
that the power supply wires have not been reversed accidentally.
3.
When the equipment is subject to EC Directives (the Low Voltage Direc-
tives), a DC power supply with reinforced insulation or double insulation
must be used for the I/O power supply.
4.
Double-check all connector wiring before turning ON the power supply.
5.
Do not pull on the cable. Doing so may separate the cable from the con-
nector.
6.
Do not bend the cable too sharply. Doing so may damage the cable.
7.
The connector pin allocation of the CJ1W-ID232/262 and OD233/263 con-
nectors is not compatible. The Unit's internal circuits may be damaged if
one of these connectors is connected.
8.
Do not connect a 24-V DC output device to a line driver input. Doing so
may damage the internal circuits.
