Chapter 1 Install a 1756 ControlNet Communication Module
Install the Module
To install the module, follow this procedure.
1. Align the circuit board with the top and bottom guides in the chassis.
2. Slide the module into the chassis making sure the module backplane
connector properly connects to the chassis backplane.
The module is properly installed when it is flush with the power supply or
other installed modules.
WARNING: When you insert or remove the module while backplane power is
on, an electrical arc can occur. This could cause an explosion in hazardous
location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
Repeated electrical arcing causes excessive wear to contacts on both the module
and its mating connector. Worn contacts may create electrical resistance that can
affect module operation.
ATTENTION: Do not force the module into the backplane connector. If you
cannot seat the module with firm pressure, check the alignment. Forcing the
module into the chassis can damage the backplane connector or the module.
