MAT 1/3 RACK/ 112404
If a transport cover is not available, the MAT power module may be mounted on a 3/4 inch thick
(or greater) piece of wood by using 8-18 thread-forming screws with a type B style point. A
screw should be used to secure the wood to each of the mounting grommets in the bottom of
the chassis.
