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.
