You will need a #2 Phillips screwdriver.
CAUTION: Explosion hazard. Removal and Insertion Under Power
is not supported in Division 2/ Zone 2. CPM and/or EPM removal
under power is not supported. The up/down rocking motion
required to remove the module causes intermittent
communications to other modules resident in the same rack. It is
recommended that before removing an active CPM or EPM, the
user first disconnects the power supply in the rack (associated
with the CPM or EPM to be removed) from the source main
power.
ATTENTION: This procedure can only be performed while off-
process.
We recommend that you proceed with extreme caution
whenever replacing any component in a control system. Be
sure the system is offline or in a safe operating mode.
Component replacements may also require downloading
appropriate configuration data to the replaced component
through Control Builder.
Wear an ESD wrist strap and observe static precautions.
Make sure all UOC configuration data and operator commands
are up to date within saved checkpoints or uploaded Control
Builder data. If not, save checkpoint, upload to Control Builder or
both.
It is recommended to bring the process to a safe and orderly
shutdown.
