Mounting
Observe these 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).
