Mount the I/O Base
To mount the I/O base on the DIN rail (Allen-Bradley part number 199-DR1; 46277-3;
EN50022), proceed as follows:
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.
ATTENTION:
This product is grounded through the DIN rail to chassis ground.
Use zinc plated yellow-chromate steel DIN rail to assure proper grounding. The
use of other DIN rail materials (for example, aluminum or plastic) that can
corrode, oxidize, or are poor conductors, can result in improper or intermittent
grounding. Secure DIN rail to mounting surface approximately every 200 mm
(7.8 in.) and use end-anchors appropriately.
