Test-fit an empty mounting between the rails and determine which holes in the rails will be used. Leave 1/2 inch between mountings. Start a screw in each of these holes, leaving 1/4-inch gap between the screw-head and rail. Install the mounting using the screws as hooks to hold it in place. Start a screw at the top of each side of the mounting and tighten. Tighten the bottom screws.

Each modem and data set plugs into the mounting and will draw 30 watts of power. The modems and data sets also operate in an ambient temperature range of 40 to 120 degrees F (4.44 to 48.8 degrees C) and a relative humidity range of 5 to 95 percent, noncondensing. The altitude limit is 10,000 feet above sea level.
