Enclosure Mounting and Cable Entries
The mounting location must be flat and provide
proper clearance, rigidity, and strength to
support the enclosure and all contained
devices.
1. Mount the enclosure using the four 0.312-
inch (8 mm) diameter holes located on the
mounting flanges with ¼-inch (M6)
hardware (see Figure 2).
•
The suggested mounting height for all
station enclosures is 48 inches (1219
mm) to the center of the bottom
mounting holes of the enclosure.
•
SP2 stations are not supplied with
conduit or cable openings.
2. Remove the front panel.
3. Drill or punch entry openings in the rear
section of the enclosure (see Figure 2).
•
The station is suitable for bottom
and/or top entry.
•
Using 70-volt/100-volt line audio
requires bottom entry.
•
Recommended
: Bottom entry prevents
condensation that may form in the
conduit from dripping onto the
termination PCBA.

The minimum material (spacing)
between entry holes is ½ inch (13
mm).
