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.
