Publication 1756-IN019C-EN-P - November 2004
Removal and Insertion Under Power
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.
European Hazardous Location Approval
If you install the module in a European Zone 2 location, consider:
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.
