Mounting

Observe the following guidelines when mounting a CVM/

CVE controller:
• Ensure that the mounting surface can support the

controller and any user-supplied enclosure.

• Mount the controller on a hard, even surface whenever

possible.

• 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

that matches the ambient conditions specified in the

Technical specifications

 section.
