Wall Mounting Using Wall Mounting Bosses
Use the wall mounting bosses (mounting surfaces) when mounting a Flex Max901e to a wall. Refer
to Figure 4.6

To wall mount with wall mount bosses
1. Measure the thickness of the surface where the housing will be located.
2. Plan the installation with enough clearance around the housing to install the cable and
cable connectors and to ensure access to all housing testpoints and internal electronic
components. You may need to shim, drill access holes, or provide cutouts.
3. Drill mounting holes 11.8 inches (30.0 cm) apart in the mounting surface if required. Use
a 9/32 inch (7 mm) diameter drill for 1/4 inch diameter bolts. See Figure 4.6 for the location
of the wall mount bosses.
4. Select appropriate length 1/4-20 UNC mounting bolts and nuts, washers (not supplied),
and lock washers to allow a threaded bolt length of 1/4 to 3/8 inch (6 to 10 mm) to extend
into the housing. Table 4.2,
Mounting Bolt Selection , lists three examples.
5. Install as shown in Figure 4.6.
6. Tighten the mounting bolts. Use 40 to 66 in-lbs (4.5 to 7.5 N · m) of torque.
Tip Use flat washers with a large outside diameter (not supplied) on any walls that are
made of compressible material.
Table 4.2 Mounting Bolt Selection
Minimum Wall Thickness Bolt Length
1/16 inch (1.6 mm) 3/8 inch (10mm)
1/4 inch (6 mm) 5/8 inch (16mm)
1/2 inch (13 mm) 7/8 inch (22mm)
CAUTION Do not torque mounting bolts more than 66 in-lbs (7.5 N·m), or more
than three to four turns, to avoid penetrating the housing and damaging the
electronics.
Tip The external testpoints for this housing are on the same surface as the wall
mount bosses. If wall mounting will restrict access to the testpoints, use an alternate
mounting design such as shimming, drilling the wall for access, providing a cutout,
or using extension mounting brackets (see Wall Mounting With Extension Mounting
Brackets (EMBs) on page 4-12). Shim only enough to gain access to the testpoints.
Testpoints can also be extended using 90° F-connector elbows with terminators.
Note The amount of torque required will depend on the mounting surface used.
