Mount the Module
The module cannot be panel-mounted. Mount the module to a DIN rail by following the steps
below.
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 module onto the
rail.
Ground the Module
The module 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, publicat
.
IMPORTANT
For effective cooling, mount the module following these guidelines.
•
Mount the module horizontally.
•
Provide a gap of at least 100 mm (3.94 in.) above and below the module.
•
Select a location where air flows freely or use an additional fan.
•
Do not mount the module over a heating device.
TIP
To remove the module 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 module 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 DIN rail to mounting surface approximately every 200 mm
(7.8 in.) and use end-anchors appropriately.
