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. 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 on the module lock on the top of the module.
4. Pull on the I/O module to remove from the base.
5. Repeat steps 1, 2, 3, and 4 for the module to the right.
6. Use a small-bladed screwdriver to rotate the orange base
locking screw to a vertical position.
This releases the locking mechanism.
7. Lift straight up to remove.
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.
