3.9 Mounting Considerations

When installing the DXP Plus digital communications system, take note of the following requirements
(figure 11 shows the mounting dimensions):
NOTE: The following instructions describe how to mount the main cabinet using a backboard;
however, you can mount the cabinet on a standard 23–inch equipment rack if you wish.
•
Always choose a secure and dry mounting location that has plenty of ventilation. Be sure that the
temperature range of the location is within 32-122 degrees F (0-50 degrees C) and that the
humidity is less than 90 percent, non-condensing.
•
Locate the equipment within four feet of a proper AC electrical outlet dedicated exclusively to
this equipment. The outlet must be a 117 VAC 15 AMP circuit with a third-wire ground
supplied to a standard electrical outlet (NEMA 5-15R)
•
Locate the equipment within 25 feet of the TELCO/PBX jacks—this is an FCC requirement. A
nominal distance of seven feet is ideal.
•
Use a reliable earth ground—a metal cold water pipe or a metal building frame ground.
•
Use a backboard of at least 3/4-inch thick plywood to mount the DXP Plus common equipment.
It is a good practice to make this backboard large enough to accommodate the main cabinet, the
expansion cabinet, and a battery backup assembly even though the initial installation may not
require all of this equipment.
•
Always bridge underlying wall studs with the backboard and drive the attaching hardware
through the backboard and through the underlying wall into the wall studs. Allow space
between the top and bottom of the main cabinet for later placement of an expansion cabinet
above the main cabinet.
