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 (RTB), if wired.
1. Unlatch the RTB handle on the I/O module.
2. Pull on the RTB handle to remove the RTB.
3. Press on the module lock on the top of the module.
4. Pull on the I/O module to remove from the base.
WARNING
When you connect or disconnect the removable terminal block (RTB)
with field-side power applied, an electrical arc can occur. This can
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.
