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.
