Wall Mounting With EMBs
Use Extension Mounting Brackets to mount the E7 Line Extender if additional space is required
between the unit and the mounting surface. The following kits are available:
■ 3.2-inch (8cm) EMB (P/N 172187-01)
■ 6-inch (15cm) 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
bosses as shown in Figure 3.7. Tighten the bolts until the EMBs are snug, but not fully
tightened.
2. Measure the thickness of the surface on which the housing will be located.
3. Plan the installation to leave 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 two mounting holes 5.5 inches (14.0 cm) apart in the mounting surface, if required.
(Refer to Figure 3.7 on page 3-11 for the location of the top strand clamp bosses.) Use a 9/32
inch (7mm) diameter drill for 1/4 inch diameter bolts.
5. Select appropriate length 1/4-20UNC mounting bolts, nuts (not supplied), washers, and lock
washers to allow a threaded bolt length of 1/4 to 3/8 inch (6 to 10mm) to extend into the
housing. See Table 3.1 on page 3-8, for several examples.
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. Use no more than 66in-lbs (7.5N·m) torque.
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:
■ 1/4-20UNC x1/2-inch bolt
■ 1/4-inch lock washer
■ 1/4-20UNC inch nut
CAUTION: Do not torque mounting bolts more than 66 in-lbs (7.5N·m), or more than
three to four full turns, to avoid penetrating the housing and damaging the electronics.
Note: Use flat washers on the back side of any mounting surface that is made of
compressible material.
Note: The amount of torque required will depend on the mounting surface used.
