Install the Module 2-5
Install the Module
Install the module before or after base installation. Make sure that you 
correctly key the mounting base before installing the module into the 
mounting base. In addition, make sure you position the mounting 
base locking screw horizontal, as referenced to the base.
1. Using a bladed screwdriver, rotate the keyswitch on the 
mounting base clockwise until the number required for the type 
of module you are installing aligns with the notch in the base.

2. Make sure the DIN rail locking screw is in the horizontal 
position. 
You cannot insert the module if you unlock the locking 
mechanism. 
3. Insert the module straight down into the mounting base,
and press to secure.
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. 
Turn the keyswitch to align
the number with the notch.
