Battery: Back-up, First Use, Installation, and Replacement
Back-up
In order to preserve back-up values for RTC and system data in the event of power off, the
battery must be connected.
First Use
The battery is protected by a removable cover
on the side of the controller.
The battery is supplied installed inside the
unit, with a plastic tab preventing contact
which must be removed by the user.
Battery Installation and Replacement
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.
Note that disconnecting the battery halts the preservation of back-up values
and causes them to be deleted.
1. Remove the battery cover from the controller as shown in the accompanying figure:
- Press the tab on the module to disengage it.
- Slide it up to remove it.
2. If you are replacing the battery, remove the
battery from its slot on the side of the
controller.
3. Insert the battery, ensuring that the polarity
is aligned with the polarity marking as shown
in the accompanying figure.
4. Replace the battery cover.
5. Dispose of the used battery according to local
and national standards and regulations.

Wiring
This equipment is designed to operate only at SELV/PELV/Class 2/Limited Power
environments.
All power supplies in the system must include double insulation. Power supply
outputs must be rated as SELV/PELV/Class 2/Limited Power.
Do not connect either the ‘Neutral’ or ‘Line’ signal of the 110/220VAC to device’s 0V
point.
Do not touch live wires.
All wiring activities should be performed while power is OFF.
Use over-current protection, such as a fuse or circuit breaker, to avoid excessive
currents into the power supply connection point.
Unused points should not be connected (unless otherwise specified). Ignoring this
directive may damage the device.
Double-check all wiring before turning on the power supply.
Caution
To avoid damaging the wire, use 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 26-12 AWG wire (0.13 mm2–3.31 mm2 )
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 a proper connection.
4. Tighten enough to keep the wire from pulling free.
Wiring Guidelines
In order to ensure that the device will operate properly and to avoid electromagnetic
interference:
Use a metal cabinet. Make sure the cabinet and its doors are properly earthed.
Use wires that are properly sized for the load.
Use shielded twisted pair cables for wiring High Speed and Analog I/O signals.
In either case, do not use the cable shield as a signal common / return path.
Route each I/O signal with its own dedicated common wire. Connect common wires
at their respective common (CM) points at the controller.
Individually connect each 0V point and each common (CM) point in the system to the
power supply 0V terminal, unless otherwise specified.
Individually connect each functional ground point ( ) to the earth of the system
(preferably to the metal cabinet chassis).
Use the shortest and thickest wires possible: less than 1m (3.3’) in length, minimum
thickness 14 AWG (2 mm2).
Connect the power supply 0V to the earth of the system.

UniStream®Built-in

Earthing the cables' shield:
Connect the cable shield to the earth of the system (preferably to the metal
cabinet chassis). Note that the shield must be connected only at one end of the
cable; it is recommended to earth the shield at the PLC-side.
Keep shield connections as short as possible.
Ensure shield continuity when extending shielded cables.
NOTE
For detailed information, refer to the document System Wiring Guidelines,
located in the Technical Library in the Unitronics’ website.
Wiring the Power Supply
The controller requires an external power supply.
In the event of voltage fluctuations or non-conformity to voltage power supply
specifications, connect the device to a regulated power supply.
Connect the +V and 0V terminals as
shown in the accompanying figure.
Connecting Ports
Ethernet
CAT-5e shielded cable with RJ45 connector
USB Device
Use the proprietary programming cable supplied with the device
USB Host
Standard USB cable with Type-A plug
Connecting Audio
Audio-Out
Use 3.5mm stereo audio plug with shielded audio cable
Note that only Pro models support this feature.

Wiring the Digital Inputs
The digital inputs are arranged in two isolated groups:
I0-I9 share common CM0
I10-I13 share common CM1
Each group may be wired together as sink or source.
Inputs I10, I11, I12 and I13 can be configured as either normal digital inputs or as high
speed inputs that can receive high speed pulse signals from sensors or shaft encoders.

Wiring the Analog Inputs
Both inputs share the common point CM2.
NOTE
Each input offers two modes: voltage or current. You can set each input
independently. The mode is determined both by wiring and by the hardware
configuration within the software application.
Voltage and current modes use distinct points. Connect only the point
associated with the selected mode; leave the other point unconnected.

Wiring the Temperature Inputs
NOTE
Each input offers three modes: thermocouple, mV or RTD. You can set each input
independently. The mode is determined both by wiring and by the hardware
configuration within the software application.
In order to ensure that the temperature inputs operate correctly, connect the points RTn+
and RTn- of unused temperature inputs together. Note that ‘n’designates input number).

About Thermocouple Isolation
Although the temperature inputs are isolated from the bus and the controller's power-
supply port, they are neither isolated from each other nor from the analog inputs.
Therefore, temperature inputs isolation may be bypassed when using an exposed-junction
(non-isolated) thermocouple in conjunction with analog inputs or another exposed-junction
thermocouple, which can lead to flow of unwanted currents through the thermocouple
wires that might interfere with thermocouple voltage reading.
In order to maintain temperature inputs isolation when using one or more of the analog
inputs or when using more than one thermocouple, either:
Use isolated-junction thermocouples, or, if you are not using the analog inputs, you may
use up to one exposed-junction thermocouple;
Electrically isolate exposed-junction thermocouples from other electrically-conductive
parts of the system.

RTD
NOTE
When connecting 3- or 4-wire RTDs, make sure to use conductors of the same
type, width, and length for all RTD wires, otherwise the accuracy will degrade.
When connecting 4-wire RTDs, use 3-wire cable and leave the unused wire
unconnected and of minimal length.

Wiring the Relay Outputs (US5-Bx-RA28, US7-Bx-RA28, US10-Bx-RA28)
To avoid risk of fire or property damage, always use a limited current source or
connect a current limiting device in series with the relay contacts
The relay outputs are arranged in two
isolated groups:
O0-O3 share the common return CM3.
O4-O7 share the common return CM4.
Increasing Contact Life Span
To increase the life span of the relay contacts and protect the controller from potential
damage by reverse EMF, connect:
a clamping diode in parallel with each inductive DC load,
a RC snubber circuit in parallel with each inductive AC load
Wiring the Source Transistor Outputs
(US5-Bx-TA30, US7-Bx-TA30, US10-Bx-TA30)
Output’s power supply
The use of any of the outputs requires
an external 24VDC power supply as
shown in the accompanying figure.
Outputs
Connect the +VO and 0VO terminals as
shown in the accompanying figure.
O0-O9 share common return 0VO.

Wiring the Analog Outputs
NOTE
The outputs are not isolated.
Each output offers two modes: voltage or current. You can set each output
independently.
The mode is determined by the hardware configuration within the software
application.
Note that if, for example, you wire the output to current input, you must also set it
to current in the software application.
CM5 is internally connected to the 0V point. To minimize EMI pickup by analog signals'
wiring, do not externally connect CM5 to the system 0V.
Do not use point CM5 for any purpose other than connecting the analog output
load. Using it for any other purpose may damage the controller.

Turn off system power before connecting or disconnecting any modules or devices.
Use proper precautions to prevent Electro-Static Discharge (ESD).
Uninstalling the Controller
1. Disconnect the power supply.
2. Remove all wiring and disconnect any installed devices according to the device’s
