About the I/O Bus Connectors
The I/O Bus connectors provide the physical and electrical connection points between
modules. The connector is shipped covered by a protective cover, protecting the connector
from debris, damage, and ESD.
The I/O Bus - Left (#4 in diagram) can be connected to either a CPU-for-Panel, a
Uni-COM™ module, to another Uni-I/O™ module or to the End Unit of a Local Expansion
Kit.
The I/O Bus - Right (#6 in diagram) can be connected to another I/O module, or to the
Base Unit of the Local Expansion Kit.
Caution  If the I/O module is located last in the configuration, and nothing is to be
connected to it, do not remove its Bus Connector Cover.

Installation

 Turn off system power before connecting or disconnecting any modules or devices.
 Use proper precautions to prevent Electro-Static Discharge (ESD).

If the Uni-I/O™ module is to be the last one in the configuration, do not remove the
cover of its I/O Bus Connector - Right.
2. Open the door of the Uni-I/O™
module and hold it as shown in the
