Install The Module - Allen-Bradley D Series Installation Instructions Manual

POINT I/O Input Modules Installation Instructions
1. Position the mounting base vertically above the installed units (adapter, power supply, or existing module).
2. Slide the mounting base down allowing the interlocking side pieces to engage the adjacent module or adapter.
3. Press firmly to seat the mounting base on the DIN rail.
The mounting base snaps into place.

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 that 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 that the DIN rail locking screw is in the horizontal position.
You cannot insert the module if the locking mechanism is unlocked.
