Install the Module Follow these steps to install the module.
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.
ATTENTION: Use caution when handling the module. One side of the module is
a heat sink, and may be very hot.
IMPORTANT Your module will resemble one of the modules shown in the illustrations. Note
that the extreme temperature (XT) versions of the modules are not shown in the
illustrations.
