Short-Range Local Expansion Kit Installation Guide

UAG-XKxxx

&UAG-XKPxxx

Use a Short-Range Local Expansion Kit to expand your I/O configuration by connecting a

UniStream™ CPU controller to Uni-I/O™ modules located on a DIN-rail.

Short-Range Local Expansion Kits are available:

Without power supply

With power supply

This enables a single CPU to support a greater

number of modules

The kit is available with cables of different lengths.

Note that the maximum number of modules supported

by a single CPU is provided in the CPU’s technical

specifications.

Before You Begin

Before installing the device, the installer must:

Read and understand this document and related technical specifications and documents

in the Technical library section of the Unitronics website.

Verify the Kit Contents.

Installation Space Considerations

Allocate space for the Base Unit and End Unit according to the dimensions in the kit’s

technical specifications. Also, consider the space required to install and connect them, as

shown in the following Installation instructions.

Installation

Turn off system power before connecting or disconnecting any modules or devices.



Use proper precautions to prevent Electro-Static Discharge (ESD).

This kit enables you to connect a UniStream™ controller to a row of Uni-I/O™ modules

located on a DIN-rail. To do this, you must:

Connect the Base Unit to the last device installed on the back of the HMI panel. This may

be the CPU-for-Panel, a Uni-COM™ module, or another Uni-I/O™ module.

Connect the End Unit to the first module in a row of Uni-I/O™ modules.

Link the End Unit into the Base Unit via the connecting cable.

If you are using a:

UAG-XKPxxx with power supply, connect it to a power source

UAG-XKxxx without power supply, earth it.

Connecting the Base Unit

1. Check the unit to which you will connect the

Base Unit to verify that its Bus Connector is

not covered.

2. Hold the Base Unit as shown in the

accompanying figure, and plug it into the last

device installed on the back of the HMI panel.

3. Click the top and bottom clips into the Guide

Tunnel of the last device.

Connecting the End Unit

1. Push the End Unit onto the DIN-rail until the clips located at the top and bottom of the

unit have snapped onto the DIN-rail.

2. Install Uni-I/O™ modules to the right of the End unit. Please refer to the specific

Installation Guide of each Uni-I/O™ module.

3. Slide the Bus Connector Lock of the first module all the way to

the left.

4. Link the units by plugging the RJ45 of the End Unit’s cable into

the port on the bottom of the Base Unit.

5. If you are using a:

UAG-XKPxxx with power supply, connect it to a power source

as described on page 4.

UAG-XKxxx without power supply, earth it.

Do not connect the cable to any device other than the Base Unit.

Do not connect the Base Unit’s cable port to any other cable or device.

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 UAG-XKPxxx supply port.

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.

Connect the 0V point of the UAG-XKPxxx directly to the power supply 0V terminal.

Connect the 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.

OTE

For detailed information, refer to the document System Wiring Guidelines, located in

the Technical Library in the Unitronics’ website.

13BWiring the Power Supply (UAG-XKPxxx)

The UAG-XKPxxx requires an external 12 or 24VDC power supply.

The 0V of the UAG-XKPxxx end unit must be connected to the HMI Panel’s 0V.

Ignoring this directive may damage the device.

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.

7BRemoving the Expansion Cable

1. Turn off the system power.

2. Unplug the cable from the Base Unit.

3. To remove the Base unit, pull the top clip up and the bottom clip down; and pull it

slowly away until the plug disengages.

4. To remove the End unit:

•Locate the Bus connector lock of the Uni-I/O™ module connected to the End Unit

and slide it to the right.

•Pull the End Unit’s top DIN-rail clip up and the bottom clip down.

•Pull the End Unit out of its place (away from the DIN rail).
