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.
Do not connect the 'Neutral or 'Line' signal of the 110/220VAC to the device's COM pins.
Double-check all wiring before turning on the power supply.

Wiring Procedures

Use crimp terminals for wiring; use 26-12 AWG wire (0.13 mm
1. Strip the wire to a length of 7±0.5mm (0.250–0.300 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·m).
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.
I/O Wiring—General
Input or output cables should not be run through the same multi-core cable or share the same wire.
Allow for voltage drop and noise interference with input lines used over an extended distance. Use wire
that is properly sized for the load.
