Symbol Meaning Description
Danger The identified danger causes physical
and property damage.
Warning The identified danger can cause
physical and property damage.
Symbols are used to highlight
information relating to the user’s
personal safety and equipment
protection throughout this document.
When these symbols appear, the
associated information must be read
carefully and understood fully. Caution Caution Use caution.
Failure to comply with appropriate safety guidelines can result in severe personal injury or
property damage. Always exercise proper caution when working with electrical equipment.
Check the user program before running it.
Do not attempt to use this device with parameters that exceed permissible levels.
Install an external circuit breaker and take appropriate safety measures against short-circuiting
in external wiring.
To avoid damaging the system, do not connect / disconnect the device when the power is on.
Caution Ascertain that terminal blocks are properly secured in place.
Environmental Considerations
Do not install in areas with: excessive or conductive dust, corrosive or flammable gas,
moisture or rain, excessive heat, regular impact shocks or excessive vibration.
Provide proper ventilation by leaving at least 10mm of space between the top and bottom
edges of the device and the enclosure walls.
Do not place in water or let water leak onto the unit.
Do not allow debris to fall inside the unit during installation.

Installing / Removing the Snap-in I/O Module
These instructions are given in the controller’s user guide, in the chapter ‘I/Os‘, under the
section ‘Installing Snap-in I/O Modules‘.
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 0V pin.
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 2–3.31 mm2) for all wiring purposes.
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.
Digital Inputs
Each group of 8 inputs has a common signal. Each group can be used as either pnp (source) or npn (sink),
when appropriately wired as shown in the following figures.
Inputs I0 and I2 can be used as normal digital inputs, as high-speed counters, or as part of a shaft encoder.
Inputs I1 and I3 can be used as normal digital inputs, as high-speed counter resets, or as part of a shaft
encoder.
The 0V signal of the inputs is isolated from the controller’s 0V signal.
Each group of inputs has its own 0V signal.
The inputs’ 0V and N signals are internally shorted on each connector.

Digital Outputs
Wiring Power Supplies
1. Connect the "positive" lead to the “V1” terminal for the relay outputs, to the “V2” terminal for
the transistor outputs.
2. In both cases, connect the “negative” lead to the “0V” terminal of each output group.
In the event of voltage fluctuations or non-conformity to voltage power supply specifications, connect the
device to a regulated power supply.
Do not connect the ‘Neutral’ or ‘Line’ signal of the 110/220VAC to the device’s 0V pin.
Relay Outputs
The 0V signal of the relay outputs is isolated from the controller’s 0V signal.
Increasing Contact Life Span
To increase the life span of the relay output
contacts and protect the device from potential
damage by reverse EMF, connect:
a clamping diode in parallel with each
inductive DC load,
an RC snubber circuit in parallel with each
inductive AC load.
