to download
The UAC-01EC2 communication module supports EtherCAT, and is compatible with the
UniStream®PLC (USC-B5/B10) controller series.
This guide provides basic installation information.
Technical specifications may be downloaded from the Unitronics website.
Note that:
UAC-01EC2 is compatible only with UniStream®PLC USC-
B5/B10.
Only one UAC-01EC2 module may be connected to a PLC.
The UAC-01EC2 must be adjacent to the CPU.
UAC-01EC2 cannot be connected to the CPU via an
expansion cable.
No other module may be installed between the CPU and
the UAC-01EC2.

About the IO/COM Bus Connectors
The IO/COM Bus connectors provide the physical and electrical connection points between
modules. The right side connector is shipped covered by a protective cover, protecting the
connector from debris, damage, and ESD.
The IO/COM Bus - Left (#3 in diagram) can only be connected directly to a CPU.
The IO/COM Bus - Right (#5 in diagram) can be connected to an I/O module, or to the
Base Unit of the Local Expansion Adapter.
Notes
UAC-01EC2 module must be next to and directly connected to a CPU
In case that the UAC-01EC2 is the only module in the configuration, to which
nothing is connected to its right: do not remove its Bus Connector Cover.
Uni-COM™ modules cannot be connected via a Local Expansion Adapter.
Installation
Turn off system power before connecting or disconnecting any module or device.
Use proper precautions to prevent Electro-Static Discharge (ESD).
Installing the UAC-01EC2 Module
1. Check the unit to which you will connect the UAC-01EC2 module. Verify that its Bus
Connector is not covered.
If the UAC-01EC2 module is the last one in the configuration, do not remove the cover
of its IO/COM Bus-Right connector.
2. Open the door of the UAC-01EC2
module and hold it as shown in the
accompanying figure.
3. Use the upper and lower guide-
tunnels (tongue & groove) to slide
the UAC-01EC2 module into place.
4. Verify that the clips located at the
top and bottom of the UAC-01EC2
module have snapped onto the DIN-
rail.
5. Slide the Bus Connector Lock all the way to
the left as shown in the accompanying figure.
6. If there is already a module located to its
right, complete the connection by sliding the
Bus Connector lock of the adjacent unit to the
left.
7. If the module is the last in the configuration,
leave the IO/COM Bus Connector covered.

Removing a Module
8. Turn off the system power.
9. Disconnect the connectors from the Ethernet and USB ports (#2,7 in the Diagram on
page 2).
10. Disconnect the UAC-01EC2 module from the adjacent units: slide its Bus Connector
Lock to the right. If there is a unit located on its right, slide the lock of this module to
the right as well.
11. On the UAC-01EC2 module, pull the top DIN-rail clip up and the bottom clip down.
12. Open the door of the UAC-01EC2 and hold it with two fingers as shown in the figure on
page 3; then pull it carefully from its place.
Wiring
All wiring activities should be performed while power is OFF.
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.
Wiring Procedure
Functional ground terminal ( )
Use a wire of minimum thickness of 14 AWG (2 mm2); terminate it with a ring or fork
crimp terminal, stud size #6.
Tighten the screw enough to make sure the ring/fork crimp terminal is not loose.
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.
Connect the functional ground terminal ( ) to the earth of the system (preferably to the
metal cabinet chassis).
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).
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.
