PA-943 Rev. C April 2021
Prepare the rack
Install the cage nuts (FA-274) into the front-rack holes for the front rack-ears in the rails. The rack holes
selected determine the placement of the instrument in the rack.
Cage nuts for the front rack-ears should be installed into the rails at the same hole spacing (vertical
height).

Install the instruments
When rack mounting restricts access to the main power cord, provide a separate main power
disconnect device, located close to the equipment and within easy reach of the operator.
Failure to disconnect all power when needed may expose personnel to hazardous voltages,
which, if contacted, could cause personal injury or death.
To complete this procedure, two people are recommended.
