Install the Module
Remove a Mounting Base
To remove a mounting base, you must remove any installed module and the
module installed in the base to the right. If the mounting base has a removable
terminal base (RTB), unlatch the RTB handle on the I/O module and pull on the
handle to remove the RTB.
1.
Pull up on the I/O module to remove it from the base.
2.
Remove the module to the right of the base you are removing, noting that
the interlocking portion of the base sits under the adjacent module.
3.
Use a screwdriver to rotate the orange DIN-rail locking screw on the
mounting base to a vertical position, noting this releases the locking
mechanism.
4.
Lift the mounting base off the DIN rail.
Wire Modules
Follow these guidelines when wiring the modules:
•
1770-4.1
.
•
We recommend that you wire correctly after confirming the signal names
of all terminals.
•
Tighten screws for communication and I/O connectors correctly.
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 to
remove power or that the area is nonhazardous before proceeding.
