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, in
accordance with the standards given in the product’s technical specification sheet.
Do not place in water or let water leak onto the unit.
Do not allow debris to fall inside the unit during installation.
Ventilation: 10mm space required between controller’s top/bottom edges & enclosure walls.
Install at maximum distance from high-voltage cables and power equipment.
Mounting
Dimensions
Note that the Snap-in I/O module thickness is 23 mm (0.9”).

Panel Mounting
Before you begin, note that the mounting panel cannot be more than 5 mm thick.
1. Make a panel cut-out of the appropriate size:
193x125mm (7.59”x4.92”).
2. Slide the controller into the cut-out, ensuring that the rubber seal is in place.
3. Push the mounting brackets into their slots on the sides of the panel as shown in the figure below.
4. Tighten the bracket’s screws against the panel. Hold the bracket securely against the unit
while tightening the screw.
5. When properly mounted, the controller is squarely situated in the panel cut-out as shown in
the accompanying figures.

Inserting the Battery
In order to preserve data in case of power-off, you must insert the battery.
The battery is supplied taped to the battery cover on the rear of the controller.
1.Remove the battery cover shown on page 3.
The polarity (+) is marked on the battery holder and on the battery.
2.Insert the battery, ensuring that the polarity symbol on the battery is:
- facing up
- aligned with the symbol on the holder
3.Replace the battery cover.
Use proper precautions to prevent Electro-Static Discharge (ESD) while servicing the
battery.
Caution
To preserve back-up values for RTC and system data during battery replacement, the
controller must be powered.
Wiring
Do not touch live wires.
Install an external circuit breaker. Guard against short-circuiting in external wiring.
Use appropriate circuit protection devices.
Unused pins should not be connected. Ignoring this directive may damage the device.
Double-check all wiring before turning on the power supply.
Caution
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 substance on stripped wire that might cause the wire
strand to break.
Install at maximum distance from high-voltage cables and power equipment.
Wiring Procedure
Use crimp terminals for wiring; use 3.31 mm² –0.13 mm² wire (12-16 AWG):
1.Strip the wire to a length of 7±0.5mm (0.270–0.300“).
2.Unscrew the terminal to its widest position before inserting a wire.
3.Insert the wire completely into the terminal to ensure a proper connection.
4.Tighten enough to keep the wire from pulling free.
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 I/O lines used over an extended distance.
Use wire that is properly sized for the load.
The controller and I/O signals must be connected to the same 0V signal.

Power Supply
The controller requires either an external 12 or 24VDC power supply.
Note: Photo is for illustration purposes only.
1. The power supply must include double insulation. Outputs must be rated as
SELV/PELV/Class 2/Limited Power.
2. Use separate wires to connect the functional
earth terminal and the 0V terminal to the
system earth ground.
3. Install an external circuit breaker. Guard
against short-circuiting in external wiring.
4. Double-check all wiring before turning
on the power supply.
5. Do not connect either the ‘Neutral’ or ‘Line’
signal of the 110/220VAC to device’s 0V pin.
6. In the event of voltage fluctuations or non-
conformity to voltage power supply
specifications, connect the device to
a regulated power supply.
Earthing the PLC+HMI
To maximize system performance, avoid electromagnetic interference by:
Mounting the controller on a metal panel.
Connect each common and ground connection directly to the earth ground of your system.
For ground wiring use the shortest and thickest possible wire.
Communication Ports
The controller comprises a USB port, 1 RS232/RS485 serial port and an Ethernet port.
The user may order and install one or both of the following modules:
An additional port (Port 2).
Available types: RS232/RS485 isolated/non-isolated
A CANbus port
For the most updated information regarding ports and their installation, please refer to the
Technical Library at www.unitronics.com.
Turn off power before making communications connections.
Caution
Always use the appropriate port adapters.
The USB port may be used for programming, OS download, and PC access.
Note that COM port 1 function is suspended when this port is physically connected to a PC.
The serial port type is RJ-11 and may be set to either RS232 or RS485 via DIP switch, in accordance
with the table shown below.
Use RS232 to download programs from a PC, and to communicate with serial devices and
applications, such as SCADA.
Use RS485 to create a multi-drop network containing up to 32 devices.

Pinouts
The pinouts below show PLC port signals.
To connect a PC to a port that is set to RS485, remove the RS485 connector, and connect the PC to
the PLC via the programming cable. Note that this is possible only if flow control signals are not used
(which is the standard case).
