Chapter Summary 20
These modules do not receive primary operational power from the
backplane. 24V DC power must be applied to your module before
installation. If power is not applied, the module position may appear
to the adapter as an empty slot in your chassis.
If using a Series B product to replace a Series A product, connect a
wire between terminals 39 and 48 on the 1794-TB3G or 1794-TB3GS
terminal base unit. If not connected, the Series B product defaults to
Series B functionality.
