ATTENTION
These modules do not receive primary operational power from the
backplane. +V and -V DC power must be applied to your module
before installation. If power is not applied, the module position will
appear to the adapter as an empty slot in your chassis.
WARNING
These module are designed so you can remove and insert them under
power. However, take special care when removing or inserting these
modules in an active process. I/O attached to any module being
removed or inserted can change states due to its input/output signal
changing conditions.
If you insert or remove the terminal base 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.
