Determine Module Slot Location
You can install the module in any slot in the ControlLogix chassis. You can
also install multiple 1756-EWEB modules in the same chassis. The figure
below shows chassis slot numbering in a 4-slot chassis. Slot 0 is the first slot
and is always the left-most slot in the rack (the first slot to the right of the
power supply).
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.
