Install the Module
Install the module before or after base installation. Make sure that
you:
• correctly keyed the mounting base before installing the
module into the mounting base
• positioned the mounting base locking screw horizontal with
reference to the base
To install the module, proceed as follows.
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 certain the DIN rail locking screw is in the horizontal
position.
You cannot insert the module if the locking mechanism is
unlocked.
3. Insert the module straight down into the mounting base and
press to secure.
The module will lock into place.
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.
