5.3 Install MCUs
Mount MCUs to Wall
The MCUs are designed to be mounted on a backboard of ¾ inch plywood, securely
fastened to the wall. Mount the MCUs vertically, side by side, using 2.75 inch spacing
center-to-center for each unit. Do not stack MCUs on top of one another.
To mount the MCUs:
1. Using a 1/8” drill bit, drill four pilot holes, on 2 inch by 12.1-inch centers.
2. If installing only one MCU, insert the #8 x 3/4 inch screws in the pilot holes and
tighten, leaving a 1/8 to 1/4 inch gap from the wall.
3. If installing more than one MCU, the ESD bonding strap(s) must be installed
between adjacent units:
3.1 Remove the screws from the bottom of adjacent units.
3.2 Place the ESD strap over the pilot holes that span two units and hold it
against the plywood backboard.
3.3 Place the star washer on top of the ESD strap.
3.4 Insert the #8 x 3/4 screw and tighten to leave 1/8 to 1/4 inch gap from the
wall.
3.5 Repeat for all ESD straps.
4. Slide the MCU over the screws until it drops in place.
5. Tighten screws fully.
6. When installing an analog interface MCU (SCA-5XX), the grounding terminal in
the rear panel of each unit must be electrically connected to earth ground.
Consult the NEC and local codes for instructions on making the connection to the
ground.
Connect MCU to Demarc Blocks
Connect the male RJ-21 connector from the appropriate demarcation block to the
designated RJ-21 connector (A or B) on each MCU. Secure the cables using the keeper.
