1-6 Install the Module
Remove a Mounting Base To remove a mounting base, you must remove any installed module,
and remove the removable terminal block (if wired).
1. Unlatch the RTB handle on the I/O module.
2. Pull on the RTB handle to remove the removable terminal block.
3. Press in on the module lock on the top of the module, and pull
up on the I/O module to remove from the base.
4. Remove the module to the right of the base you are removing.
The interlocking portion of the base sits under the adjacent
module.
5. Use a small-bladed screwdriver to rotate the orange DIN-rail
locking screw on the mounting base to a vertical position,
releasing the locking mechanism.
6. Lift the mounting base straight up to remove.
WARNING
When you connect or disconnect the removable
terminal block (RTB) with field-side power applied,
an electrical arc can occur. This could cause an
explosion in hazardous location installations.
Be sure that power is removed or the area is
nonhazardous before proceeding.
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 that power is removed or the area is
nonhazardous 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.
