Wall Mounting With Extension Mounting Brackets (EMBs)
Use EMBs to mount a Flex Max901e if additional space is required between the unit and the
mounting surface. The following kits are available:
■
3.2-inch (8 cm) EMB (P/N 172187-01)
■
6-inch (15 cm) EMB (P/N 172187-03)

To wall mount with EMBs
1. Place the lock washers on the bolts supplied with the EMBs and bolt the EMBs to the top
strand clamp bosses (mounting surfaces) as shown in Figure 4.7. Tighten the bolts until the
EMBs are snug but not fully tightened.
2. Measure the thickness of the surface where the housing will be located.
3. Plan the installation to provide enough clearance around the housing to install the cable
and cable connectors and to ensure access to all housing testpoints and internal electronic
components.
4. Drill mounting holes 8.5 inches (21.6 cm) apart in the mounting surface as required. Use a
9/32 inch (7 mm) diameter drill for 1/4-inch diameter bolts. See Figure 4.7 for the location
of the wall mount bosses.
5. Select appropriate length 1/4-20 UNC mounting bolts and nuts, flat 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 on page 4-10 lists three examples. Use flat washers on the back
side of any mounting surface made of compressible material.
6. Align the EMB flange holes with the wall mounting holes. Insert the bolts with flat washers
through the aligned holes, slip a lock washer over the end of each bolt, and thread and
finger tighten the nuts onto the bolts.
7. Tighten the mounting bolts using no more than 66 in-lbs (7.5 N·m) of torque, but the
amount of torque will depend on the mounting surface used.
Note EMBs are not included with the unit but may be purchased separately. Contact
C-COR for ordering information. Each EMB kit includes the following additional
mounting hardware:
■
1/4-20 UNC x 1/2-inch bolt
■
1/4-inch lock washer
■
1/4-20 UNC nut
Tip Use flat washers with a large outside diameter (not supplied) on any walls that are
made of compressible material.
