powered on and the ground lug is being used to ground the unit, first move

the ground connection to the ground lug located on the Controller Module.

The SDIDU™ retains its current configuration when a module is removed, unless that

module is the Controller Module. In which case, the IP addresses will need to be

reprogrammed.

3.9.2Installing a Module

1. Modules are static sensitive and should only be handled in an ESD-safe

environment. When packaging modules for shipment or storage, place in an ESD

bag.

2. Line up the module board with the guides in the chassis and slide the module into

the SDIDU™. Figure 3-25 shows a photo of the guides. As the module face plate

comes flush with the face of the SDIDU™, connectors on the rear of the module

will engage with the SDIDU™ backplane. It is possible to encounter interference

from adjacent module rear panels. If this occurs, loosen the thumbscrews holding

the neighboring panels and shift them as necessary to ensure fit.

a. The Mini IO Module only has one guide on the right side. Take care to insert

the Mini IO module carefully and correctly engage the rear connector with its

mate on the Standard IO Module.
