Mounting
Observe the following guidelines when mounting a
controller:
• Ensure the mounting surface can support the
controller, DIN rail, and any user-supplied enclosure.
• Mount the controller horizontally on 35 mm DIN rail
whenever possible.
• Mount the controller in the proper mounting position.
• Mount the controller on a hard, even surface whenever
possible in wall-mount applications.
• Use shims or washers to mount the controller securely
and evenly on the mounting surface.
• Mount the controller in an area free of corrosive vapors
and observe the Ambient Conditions requirements in
Table 11.
