Installing the Module
You can install or remove the module while chassis power is applied.
1. Align the circuit board with the top and bottoms chassis guides.
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.
WARNING
!
When you connect or disconnect the Removable Terminal
Block (RTB) with field side power applied, 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.
