Installing The Wall Box Or Mounting Bracket - Extron electronics USB HUB4 AAP User Manual

Installing the wall box or mounting bracket

Use a listed one-gang sized wall box or mounting bracket for the HUB4 MAAP or a listed
two-gang box or bracket for the AAP model. Install cables into the wall, furniture, or
conduits before installing the wall box or bracket.
NOTE: The illustrations in this section show examples of a one-gang box mounting. The
procedures for mounting to a two-gang box are the same.
If using a wall box, the mounting site must be deep enough for both the box and the cables.
The box should be at least 2.5 inches (6.4 cm) deep.
1. Place the wall box or mounting bracket against the installation surface and mark
guidelines for the opening on the wall or furniture.
2. Cut out the material from within the marked area.
3. Insert the wall box or bracket to check the size and fit of the opening. Enlarge or
smooth the edges of the opening as needed.
4. If using a wall box, feed the cables through the punched out holes in the box and
secure the cable clamps to provide strain relief.
5. Exposed cable shields (braids or foil) are potential sources of short circuits. Trim back or
insulate shields with heat shrink (see figure 9).

CAUTION: To prevent short circuits, cut back the outer foil shield to the point where
the cable exits the cable clamp. Both braided and foil shields should be connected
to an equipment ground at the other end of the cable.
ATTENTION : Afin d'éviter les court circuits, réduisez le blindage en aluminium
extérieur jusqu'à ce que le câble sorte de la cosse de câble. Le blindage tressé et
le blindage en aluminium devraient être connectés à la masse d'un équipement à
l'autre bout du câble.
6.
Insert the wall box or mounting bracket into the opening, and attach it to the wall, stud,
or furniture, leaving the front edge flush with the outer wall or furniture surface (see
figure 10 on the next page).
