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.
