General Precautions

❏The VME module front panel screws should be properly tightened for good grounding.

For minimum RF emissions, it is essential that the foregoing conditions be implemented. Failure to do so could compromise the RFI compliance of the system.

This product, as configured and shipped by Motorola, has been designed and tested for compliance with the following RFI standards and product safety regulations:

❏Electromagnetic Compatibility: FCC class A; European CE Class A

❏Safety: UL 1950; CSA C22.2/950; VDE EN 60 950; IEC 950

It is the customer’s responsibility to verify compliance if the customer makes changes or additions to the "as-shipped" configuration.

General Precautions

❏Ensure that the air space above and below the chassis is not blocked, and that the inlet screens and optional air filter are clean.

❏The air inlet temperature must not exceed 40 degrees Celsius. If the MVME956AC is installed in a rack with other chassis, be sure that each chassis in the rack is provided with its own supply of fresh cooling air. Do not use air heated by one chassis to “cool” another chassis.

❏All unused VME module slots must be covered to prevent cooling air and/or RF emissions from escaping from the chassis.

❏The chassis should be used only in a clean environment such as an office or lab.
