Mounting
Observe the following guidelines when mounting an
expansion module:
• Ensure the mounting surface can support the
expansion module, DIN rail, and any user-
supplied enclosure.
• Mount the expansion module horizontally on 35
mm DIN rail whenever possible.
• Mount the expansion module in the proper
mounting position (Figure 2).
• Mount the expansion module on a hard, even
surface whenever possible in wall-mount
applications.
• Use shims or washers to mount the expansion
module securely and evenly on the mounting
surface.
• Mount the expansion module in an area free
of corrosive vapors and observe the Ambient
Conditions requirements in Table 10.
• Provide for sufficient space around the expansion
module for cable and wire connections for easy
cover removal and good ventilation through
the expansion module (50 mm [2 in.] minimum
on the top, bottom, and front of the expansion
module).
• Do not mount the expansion module on surfaces
prone to vibration, such as duct work.
• Do not mount the expansion module in areas
where electromagnetic emissions from other
devices or wiring can interfere with expansion
module communication.
