Chapter 2: Installing a ControlLogix 1756sc-CTR8-SC Module
2-5
Owner’s Guide 0300199-01 Rev. D
Key the RTB to prevent inadvertently making the wrong wire connections to
your module. Use a unique keying pattern for each module. You can use a
minimum of one key.
When the RTB mounts onto the module, keying positions will match up. For
example, if you place a U-shaped keying band in position #4 on the module, you
cannot place a wedge-shaped tab in #4 on the RTB or your RTB will not mount
on the module.
We recommend that you use a unique keying pattern for each slot in the chassis.
1.
Key the module. Insert the U-shaped band with the longer side near the
terminals. Push the band onto the module until it snaps into place.
2.
Key the RTB in positions that correspond to un-keyed module positions.
Insert the wedge-shaped tab on the RTB with the rounded edge first.
3.
Push the tab onto the RTB until it stops.
4.
Reposition the tabs to rekey future module applications.
