Connecting Expansion Modules
An adapter provides the interface between the OPLC and an expansion module. To connect the I/O module to
the adapter or to another module:
1.
Push the module-to-module connector into the port located on the right side of the device.
Note that there is a protective cap provided with the adapter. This cap covers the port of the final
I/O module in the system.
◼
To avoid damaging the system, do not connect or disconnect the device when the
power is on.

Wiring
◼
Do not touch live wires.
◼
Unused pins should not be connected. Ignoring this directive may damage the device.
◼
Double-check all wiring before turning on the power supply.
◼
Do not connect the 'Neutral or 'Line' signal of the 110/220VAC to the device's 0V pin.
◼
In the event of voltage fluctuations or non-conformity to voltage power supply specifications,
connect the device to a regulated power supply.
◼
Double-check all the wiring before turning on the power supply.
Wiring Procedures
Use crimp terminals for wiring; use 26-14 AWG wire (0.13 mm
1.
Strip the wire to a length of 7±0.5mm (0.250–0.2.08 inches).
2.
Unscrew the terminal to its widest position before inserting a wire.
3.
Insert the wire completely into the terminal to ensure that a proper connection can be made.
4.
Tighten enough to keep the wire from pulling free.
◼
To avoid damaging the wire, do not exceed a maximum torque of 0.5 N·m (5 kgf·cm).
◼
Do not use tin, solder, or any other substance on stripped wire that might cause the wire strand to break.
◼
Install at maximum distance from high-voltage cables and power equipment.
