Install the Module in the Rack
If you have not already installed and configured your ControlLogix processor and
power supply, please do so before installing the MVI56-DH485R 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 MVI56-DH485R 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. This could cause an explosion in hazardous location installations. 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.
1
Turn power OFF.
2
Align the module with the top and bottom guides, and slide it into the rack
until the module is firmly against the backplane connector.
3
With a firm but steady push, snap the module into place.
4
Check that the holding clips on the top and bottom of the module are securely
in the locking holes of the rack.
