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 controller
and its mating connector on the chassis. Worn contacts may create electrical
resistance that can affect controller operation.
