Install the Module
The module can be installed before or after base installation. 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.
1. Using a bladed screwdriver, rotate the keyswitch 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.
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.
ATTENTION: Do not remove or replace an Adapter Module while power is
applied. Interruption of the backplane can result in unintentional operation or
machine motion.
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.
