2.2 Installing an I/O Module
Make sure that the mounting base is correctly keyed before installing the module
into the mounting base. In addition, make sure the mounting base locking screw
is positioned horizontal referenced to the base.
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 non-hazardous before proceeding.
1. Using a bladed screwdriver, rotate the key switch on the mounting base
clockwise until the number required for the type of module being installed
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 locks into place.
