Mounting
Observe these guidelines when mounting an IOM
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 (1.4 in.) 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.
