Mount the Controller
The controller cannot be panel-mounted. Mount the controller to a DIN rail by following these
steps.
1. Hook the top slot over the DIN rail.
2. Insert a flathead screwdriver into the gap
between the housing and the latch and pull
the latch downward.
3. Hold the latch down as you push the housing
back onto the DIN rail.
4. Release the latch to lock the device onto the
rail.
Ground the Controller
The controller is functionally grounded through its DIN rail connection. A protective
earth-ground connection is required and is provided through a separate grounding screw on the
upper left of the housing and marked with the grounding symbol .
You must also provide an acceptable grounding path for each device in your application. For
more information on proper grounding guidelines, refer to the Industrial Automation Wiring
and Grounding Guidelines, publication
1770-4.1 .
IMPORTANT For effective cooling, mount the controller following these guidelines.
•
Mount the controller horizontally.
•
Provide a gap of at least 100 mm (3.94 in.) above and below the controller.
•
Select a location where air flows freely or use an additional fan.
•
Do not mount the controller over a heating device.
TIP To remove the controller from the DIN rail, insert a flathead screwdriver
into the gap between the housing and the latch and pull the latch
downward as you lift the controller off of the rail.
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 the DIN rail to the mounting surface approximately every
200 mm (7.8 in.) and use end-anchors appropriately.
