2.
Slide the mounting base down to make the interlocking side pieces engage the
adjacent module or adapter.
3.
Press firmly to seat the mounting base on the DIN rail.
The mounting base snaps into place. Be sure that the orange DIN rail locking
screw is in the horizontal position and that it has engaged the DIN rail.
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.

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.
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.
To install the module, proceed as follows.
1.
Use a bladed screwdriver to 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.
Verify the DIN rail locking screw is in the horizontal position.
You cannot insert the module if the locking mechanism is unlocked.
