Shield Connections
By design, the module is isolated from ground. All shield connections on this
connector and the lower base connector are common to one another (a “shield
bus”), but otherwise isolated.
Shield connections are provided as a termination point for cable screens/
shields, one or more can be used to connect the shield bus to a local ground of
your choice.

IMPORTANT When working with the shield bus, remember the following:
• The shield bus of each main and expansion module must be individually
connected to ground by at least one shield pin that is wired directly to
ground.
• For installations where EMI problems are identified, or are anticipated,
wire cable shields directly to ground rather than to the shield bus of the
module.
