Installing 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-LTQ 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-LTQ 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.

5 Make a note of the slot location. You must identify the slot in which the

module is installed in order for the sample program to work correctly. Slot
numbers are identified on the green circuit board (backplane) of the
ControlLogix rack.

6 Turn power ON.

Note: If you insert the module improperly, the system may stop working, or may behave

unpredictably.
