Install the Module
To install the module on the DIN rail, proceed as follows.
1. Position the module vertically above the DIN rail
2. Press down firmly to install the module on the DIN rail.
The locking mechanism will lock the module to the DIN rail.
3. Remove the safety end cap by sliding it up to expose the
backplane and power interconnections.
ATTENTION
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
Do not discard the end cap. Use this end cap to 
cover the exposed interconnections on the last 
mounting base on the DIN rail. Failure to do so 
could result in equipment damage or injury from 
electric shock.
