Mounting
The Model 703-104 Indoor EPL Amplifier Enclosure is not supplied with openings for conduit or cable
because the placement will vary according to the application. Drill or punch these openings using the
template supplied before mounting the enclosure. We highly recommend using only the bottom entry to
prevent moisture from dripping onto the terminals or PCBAs. The best location for conduit holes is along
the bottom of the enclosure near the rear surface. If the top opening is to be used, carefully seal around the
fitting to prevent moisture from entering.
For specific details including mounting hole dimensions, refer to Figure 1. There are four 5/16-inch
diameter mounting holes in the corners of the amplifier enclosure. The suggested mounting height for all
station enclosures is 54 inches (137 cm) to the centerline of the enclosure.
N OTE : Labels denoting which party line(s) is configured as the emergency party line are included in an
envelope inside the enclosure. The labels are for Party Line 1, Party Line 2, and Party Lines 1 and 2
configurations. Apply the appropriate label inside your enclosure.
