Installing The Module In The Rack - ProSoft Technology ControlLogix MVI56E-SMGC User Manual

MVI56E-SMGC ♦ ControlLogix™ Platform
Enhanced FMC722 TPU General Communication Module

1.3 Installing the Module in the Rack

Make sure your ControlLogix processor and power supply are installed and configured,
before installing the MVI56E-SMGC module. Refer to your Rockwell Automation product
documentation for installation instructions.
Warning: You must follow all safety instructions when installing this or any other electronic devices. Failure
to follow safety procedures could result in damage to hardware or data, or even serious injury or death to
personnel. Refer to the documentation for each device you plan to connect to verify that suitable safety
procedures are in place before installing or servicing the device.
After you have checked the placement of the jumpers, insert the MVI56E-SMGC into the
ControlLogix chassis. Use the same technique recommended by Rockwell Automation
to remove and install ControlLogix modules.
Warning: When you insert or remove the module while backplane power is on, an electrical arc can occur.
An electrical arc can cause personal injury or property damage by sending an erroneous signal to the
system's actuators. This can cause unintended machine motion or loss of process control. Electrical arcs
may also cause an explosion when they happen in a hazardous environment. Verify that power is removed
or the area is non-hazardous 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.
Note: If you insert the module improperly, the system may stop working or may behave unpredictably.
Note: When using the XT version (if applicable), you must use the 1756-A5XT or 1756-A7LXT chassis to
uphold the XT specifications. In these chassis, modules are spaced further apart than in standard
ControlLogix chassis. Blank spacers are inserted between active modules.
